s are common resources, their effectiveness has not been well studied. The most commonly adopted method of suicide varies from country to country and is partly related to the availability of effective means. Common methods of suicide include hanging, pesticide poisoning, and firearms. Suicides resulted in 828,000 deaths globally in 2015, an increase from 712,000 deaths in 1990.. For the number 828,000, see Table 5, line "Self-harm", second column (year 2015). For the number 712,000, see Table 2, line "Self-harm", first column (year 1990) This makes suicide the 10th

to 3.5 times higher in the developed world. Suicide is generally most common among those over the age of 70; however, in certain countries, those aged between 15 and 30 are at the highest risk. Europe had the highest rates of suicide by region in 2015. There are an estimated 10 to 20 million non-fatal attempted suicides every year. Non-fatal suicide attempts may lead to injury and long-term disabilities. In the Western world, attempts are more common among young people and women. Views on suicide have been influenced by broad existential themes such as religion, honor, and the meaning of life. The Abrahamic religions traditionally consider suicide as an offense towards God due to the belief in the sanctity of life. During the samurai era in Japan, a form of suicide known as
seppuku , sometimes referred to as hara-kiri (, , a native Japanese kun reading), is a form of Japanese ritual suicide by disembowelment. It was originally reserved for samurai in their code of honour but was also practised by other Japanese people ...

Suicide and attempted suicide, while previously illegal, are no longer so in most Western countries. It remains a criminal offense in some countries. In the 20th and 21st centuries, suicide has been used on rare occasions as a form of protest, and kamikaze and

is thoughts of ending one's life but not taking any active efforts to do so. It may or may not involve exact planning or intent. In a murder–suicide (or homicide–suicide), the individual aims at taking the lives of others at the same time. A special case of this is extended suicide, where the murder is motivated by seeing the murdered persons as an extension of their self. Suicide in which the reason is that the person feels that they are not part of society is known as

On the other hand, the American Psychological Association lists "committed suicide" as a term to avoid because it "frame suicide as a crime". Some advocacy groups recommend using the terms ''took his/her own life'', ''died by suicide'', or ''killed him/herself'' instead of ''committed suicide''. The Associated Press Stylebook recommends avoiding "committed suicide" except in direct quotes from authorities. The ''

Risk factors

Factors that affect the risk of suicide include mental disorders, drug misuse,

. Mental disorders and substance misuse frequently co-exist. Other risk factors include having previously attempted suicide, the ready availability of a means to take one's life, a family history of suicide, or the presence of traumatic brain injury. For example, suicide rates have been found to be greater in households with firearms than those without them. Socio-economic problems such as unemployment, poverty, homelessness, and

may trigger suicidal thoughts. Suicide might be rarer in societies with high social cohesion and moral objections against suicide. About 15–40% of people leave a suicide note. War veterans have a higher risk of suicide due in part to higher rates of mental illness, such as post-traumatic stress disorder, and physical health problems related to war. Genetics appears to account for between 38% and 55% of suicidal behaviors. Suicides may also occur as a local

of cases. Most research does not distinguish between risk factors that lead to thinking about suicide and risk factors that lead to suicide attempts. Risks for suicide attempt rather than just thoughts of suicide include a high pain tolerance and a reduced fear of death.


Mental illness

Mental illness is present at the time of suicide 27% to more than 90% of the time. Of those who have been hospitalized for suicidal behavior, the lifetime risk of suicide is 8.6%. Comparatively, non-suicidal people hospitalized for affective disorders have a 4% lifetime risk of suicide. Half of all people who die by suicide may have major depressive disorder; having this or one of the other mood disorders such as bipolar disorder increases the risk of suicide 20-fold. Other conditions implicated include schizophrenia (14%), personality disorders (8%), obsessive–compulsive disorder, and post-traumatic stress disorder. Those with
autism The autism spectrum, often referred to as just autism or in the context of a professional diagnosis autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental condition (or conditions) characterized by difficulti ...

s are another high risk condition. Around 22% to 50% of people suffering with gender dysphoria have attempted suicide, however this greatly varies by region. Among approximately 80% of suicides, the individual has seen a physician within the year before their death, including 45% within the prior month. Approximately 25–40% of those who died by suicide had contact with mental health services in the prior year.
Antidepressant Antidepressants are a class of medication used to treat major depressive disorder, anxiety disorders, chronic pain conditions, and to help manage addictions. Common side-effects of antidepressants include dry mouth, weight gain, dizziness, hea ...
s of the SSRI class appear to increase the frequency of suicide among children but do not change the risk among adults. An unwillingness to get help for mental health problems also increases the risk.


Previous attempts

A previous history of suicide attempts is the most accurate predictor of suicide. Approximately 20% of suicides have had a previous attempt, and of those who have attempted suicide, 1% die by suicide within a year and more than 5% die by suicide within 10 years.


Self-harm

Non-suicidal self-harm is common with 18% of people engaging in self-harm over the course of their life. Acts of self-harm are not usually suicide attempts and most who self-harm are not at high risk of suicide. Some who self-harm, however, do still end their life by suicide, and risk for self-harm and suicide may overlap. Individuals who have been identified as self-harming after being admitted to hospital are more likely to die by suicide.


Psychosocial factors

A number of psychological factors increase the risk of suicide including: hopelessness, loss of pleasure in life, depression, anxiousness, agitation, rigid thinking, rumination, thought suppression, and poor coping skills. A poor ability to solve problems, the loss of abilities one used to have, and poor impulse control also play a role. In older adults, the perception of being a burden to others is important. Those who have never married are also at greater risk. Recent life stresses, such as a loss of a family member or friend or the loss of a job, might be a contributing factor. Certain personality factors, especially high levels of
neuroticism In the study of psychology, neuroticism has been considered a fundamental personality trait. For example, in the Big Five approach to personality trait theory, individuals with high scores for neuroticism are more likely than average to be moody ...
and introvertedness, have been associated with suicide. This might lead to people who are isolated and sensitive to distress to be more likely to attempt suicide. On the other hand, optimism has been shown to have a protective effect. Other psychological risk factors include having few reasons for living and feeling trapped in a stressful situation. Changes to the stress response system in the brain might be altered during suicidal states. Specifically, changes in the

is also a factor, with heightened relative poverty compared to those around a person increasing suicide risk. Over 200,000 farmers in India have died by suicide since 1997, partly due to issues of debt. In China, suicide is three times as likely in rural regions as urban ones, partly, it is believed, due to financial difficulties in this area of the country. The time of year may also affect suicide rates. There appears to be a decrease around Christmas, but an increase in rates during spring and summer, which might be related to exposure to sunshine. Another study found that the risk may be greater for males on their birthday. Being religious may reduce one's risk of suicide while beliefs that suicide is noble may increase it. This has been attributed to the negative stance many religions take against suicide and to the greater connectedness religion may give.

s, among religious people, appear to have a lower rate of suicide; however, the data supporting this is not strong. There does not appear to be a difference in rates of attempted suicide. Young women in the Middle East may have higher rates.


Substance misuse

Substance misuse Substance abuse, also known as drug abuse, is the use of a drug in amounts or by methods which are harmful to the individual or others. It is a form of substance-related disorder. Differing definitions of drug abuse are used in public health, ...
is the second most common risk factor for suicide after major depression and bipolar disorder. Both chronic substance misuse as well as acute intoxication are associated. When combined with personal grief, such as bereavement, the risk is further increased. Substance misuse is also associated with mental health disorders. Most people are under the influence of sedative-hypnotic drugs (such as alcohol or benzodiazepines) when they die by suicide, with alcoholism present in between 15% and 61% of cases. Use of prescribed benzodiazepines is associated with an increased rate of suicide and attempted suicide. The pro-suicidal effects of benzodiazepines are suspected to be due to a psychiatric disturbance caused by side effects, such as disinhibition, or withdrawal symptoms. Countries that have higher rates of alcohol use and a greater density of bars generally also have higher rates of suicide. About 2.2–3.4% of those who have been treated for alcoholism at some point in their life die by suicide. Alcoholics who attempt suicide are usually male, older, and have tried to take their own lives in the past. Between 3 and 35% of deaths among those who use

has a high correlation with suicide. In those who use cocaine, the risk is greatest during the withdrawal phase. Those who used inhalants are also at significant risk with around 20% attempting suicide at some point and more than 65% considering it. Smoking cigarettes is associated with risk of suicide. There is little evidence as to why this association exists; however, it has been hypothesized that those who are predisposed to smoking are also predisposed to suicide, that smoking causes health problems which subsequently make people want to end their life, and that smoking affects brain chemistry causing a propensity for suicide. Cannabis, however, does not appear to independently increase the risk.


Medical conditions

There is an association between suicidality and physical health problems such as chronic pain, traumatic brain injury, cancer,
chronic fatigue syndrome Chronic fatigue syndrome (CFS), also called myalgic encephalomyelitis (ME) or ME/CFS, is a complex, debilitating, long-term medical condition. The causes and mechanisms of the disease are not fully understood. Distinguishing core symptoms are ...

. The diagnosis of cancer approximately doubles the subsequent frequency of suicide. The prevalence of increased suicidality persisted after adjusting for depressive illness and alcohol abuse. Among people with more than one medical condition the frequency was particularly high. In Japan, health problems are listed as the primary justification for suicide. Sleep disturbances, such as insomnia and sleep apnea, are risk factors for depression and suicide. In some instances, the sleep disturbances may be a risk factor independent of depression. A number of other medical conditions may present with symptoms similar to mood disorders, including

).


Occupational factors

Certain occupations carry an elevated risk of self-harm and suicide, such as military careers. Research in several countries has found that the rate of suicide among former armed forces personnel in particular, and young veterans especially, is markedly higher than that found in the general population.


Media

The media, including the Internet, plays an important role. Certain depictions of suicide may increase its occurrence, with high-volume, prominent, repetitive coverage glorifying or romanticizing suicide having the most impact. When detailed descriptions of how to kill oneself by a specific means are portrayed, this method of suicide can be imitated in vulnerable people. This phenomenon has been observed in several cases after press coverage. In a bid to reduce the adverse effect of media portrayals concerning suicide report, one of the effective methods is to educate journalists on how to report suicide news in a manner that might reduce that possibility of imitation and encourage those at risk to seek for help. When journalists follow certain reporting guidelines the risk of suicides can be decreased. Getting buy-in from the media industry, however, can be difficult, especially in the long term. This trigger of suicide contagion or copycat suicide is known as the "Werther effect", named after the protagonist in Goethe's '' The Sorrows of Young Werther'' who killed himself and then was emulated by many admirers of the book. This risk is greater in adolescents who may romanticize death. It appears that while news media has a significant effect, that of the entertainment media is equivocal. It is unclear if searching for information about suicide on the Internet relates to the risk of suicide. The opposite of the Werther effect is the proposed "Papageno effect", in which coverage of effective coping mechanisms may have a protective effect. The term is based upon a character in

's opera '' The Magic Flute''—fearing the loss of a loved one, he had planned to kill himself until his friends helped him out. As a consequence, fictional portrayals of suicide, showing alternative consequences or negative consequences, might have a preventive effect, for instance fiction might normalize mental health problems and encourage help-seeking.


Other factors

Trauma is a risk factor for suicidality in both children and adults. Some may take their own lives to escape
bullying Bullying is the use of force, coercion, hurtful teasing or threat, to abuse, aggressively dominate or intimidate. The behavior is often repeated and habitual. One essential prerequisite is the perception (by the bully or by others) of an imba ...
or prejudice. A history of childhood sexual abuse and time spent in foster care are also risk factors. Sexual abuse is believed to contribute to approximately 20% of the overall risk. Significant adversity early in life has a negative effect on problem-solving skills and memory, both of which are implicated in suicidality. Problem gambling is associated with increased suicidal ideation and attempts compared to the general population. Between 12 and 24% of pathological gamblers attempt suicide. The rate of suicide among their spouses is three times greater than that of the general population. Other factors that increase the risk in problem gamblers include concomitant mental illness, alcohol, and drug misuse. Genetics might influence rates of suicide. A family history of suicide, especially in the mother, affects children more than adolescents or adults. Adoption studies have shown that this is the case for biological relatives, but not adopted relatives. This makes familial risk factors unlikely to be due to imitation.

rate is 36% for suicidal ideation and 17% for suicide attempts. An evolutionary explanation for suicide is that it may improve inclusive fitness. This may occur if the person dying by suicide cannot have more children and takes resources away from relatives by staying alive. An objection is that deaths by healthy adolescents likely does not increase inclusive fitness.

Rational

Rational suicide is the reasoned taking of one's own life. However, some consider suicide as never being rational. Euthanasia and assisted suicide are accepted practices in a number of countries among those who have a poor quality of life without the possibility of getting better. They are supported by the legal arguments for a right to die. The act of taking one's life for the benefit of others is known as altruistic suicide. An example of this is an elder ending his or her life to leave greater amounts of food for the younger people in the community.

Methods

The leading method of suicide varies among countries. The leading methods in different regions include hanging, pesticide poisoning, and firearms. These differences are believed to be in part due to availability of the different methods. A review of 56 countries found that hanging was the most common method in most of the countries, accounting for 53% of male suicides and 39% of female suicides. Worldwide, 30% of suicides are estimated to occur from pesticide poisoning, most of which occur in the developing world. The use of this method varies markedly from 4% in Europe to more than 50% in the Pacific region. It is also common in Latin America due to the ease of access within the farming populations. In many countries, drug overdoses account for approximately 60% of suicides among women and 30% among men. Many are unplanned and occur during an acute period of ambivalence. The death rate varies by method: firearms 80–90%, drowning 65–80%, hanging 60–85%, jumping 35–60%, charcoal burning 40–50%, pesticides 60–75%, and medication overdose 1.5–4.0%. The most common attempted methods of suicide differ from the most common methods of completion; up to 85% of attempts are via drug overdose in the developed world. In China, the consumption of pesticides is the most common method. In Japan, self-disembowelment known as
seppuku , sometimes referred to as hara-kiri (, , a native Japanese kun reading), is a form of Japanese ritual suicide by disembowelment. It was originally reserved for samurai in their code of honour but was also practised by other Japanese people ...
(''harakiri'') still occurs; however, hanging and jumping are the most common. Jumping to one's death is common in both Hong Kong and Singapore at 50% and 80% respectively. In Switzerland, firearms are the most frequent suicide method in young males, although this method has decreased since guns have become less common. In the United States, 50% of suicides involve the use of firearms, with this method being somewhat more common in men (56%) than women (31%). The next most common cause was hanging in males (28%) and self-poisoning in females (31%). Together, hanging and poisoning constituted about 42% of U.S. suicides ().

Low levels of brain-derived neurotrophic factor (BDNF) are both directly associated with suicide and indirectly associated through its role in major depression, posttraumatic stress disorder, schizophrenia and obsessive–compulsive disorder. Post-mortem studies have found reduced levels of BDNF in the hippocampus and prefrontal cortex, in those with and without psychiatric conditions.

Prevention

Suicide prevention is a term used for the collective efforts to reduce the incidence of suicide through preventive measures. Protective factors for suicide include support, and access to therapy. About 60% of people with suicidal thoughts do not seek help. Reasons for not doing so include low perceived need, and wanting to deal with the problem alone. Despite these high rates, there are few established treatments available for suicidal behavior. Reducing access to certain methods, such as firearms or toxins such as

and pesticides, can reduce risk of suicide by that method. This may be in part because suicide is often an impulsive decision, with up to 70% of near-fatal suicide attempts made after less than one hour of deliberation—thus, reducing access to easily-accessible methods of suicide may make impulsive attempts less likely to succeed. Other measures include reducing access to charcoal (for burning) and adding barriers on bridges and subway platforms. Treatment of drug and alcohol addiction, depression, and those who have attempted suicide in the past, may also be effective. Some have proposed reducing access to alcohol as a preventive strategy (such as reducing the number of bars). In young adults who have recently thought about suicide,

Screening

There is little data on the effects of screening the general population on the ultimate rate of suicide. Screening those who come to the emergency departments with injuries from self-harm have been shown to help identify suicide ideation and suicide intention. Psychometric tests such as the Beck Depression Inventory or the
Geriatric Depression Scale The Geriatric Depression Scale (GDS) is a 30-item self-report assessment used to identify depression in the elderly. The scale was first developed in 1982 by J.A. Yesavage and others. Description In the Geriatric Depression Scale, questions are ...

As there is a high rate of people who test positive via these tools that are not at risk of suicide, there are concerns that screening may significantly increase mental health care resource utilization. Assessing those at high risk, though, is recommended. Asking about suicidality does not appear to increase the risk.


Mental illness

In those with mental health problems, a number of treatments may reduce the risk of suicide. Those who are actively suicidal may be admitted to psychiatric care either voluntarily or involuntarily. Possessions that may be used to harm oneself are typically removed. Some clinicians get patients to sign

Epidemiology

Approximately 1.4% of people die by suicide, a mortality rate of 11.6 per 100,000 persons per year. Suicide resulted in 842,000 deaths in 2013 up from 712,000 deaths in 1990. Rates of suicide have increased by 60% from the 1960s to 2012, with these increases seen primarily in the developing world. Globally, /2009, suicide is the tenth leading cause of death. For every suicide that results in death there are between 10 and 40 attempted suicides. Suicide rates differ significantly between countries and over time. As a percentage of deaths in 2008 it was: Africa 0.5%, South-East Asia 1.9%, Americas 1.2% and Europe 1.4%. Rates per 100,000 were: Australia 8.6, Canada 11.1, China 12.7, India 23.2, United Kingdom 7.6, United States 11.4 and South Korea 28.9. It was ranked as the 10th leading cause of death in the United States in 2016 with about 45,000 cases that year. Rates have increased in the United States in the last few years, with the highest value being in 2017 (the most recent data). In the United States, about 650,000 people are seen in emergency departments yearly due to attempting suicide. The United States rate among men in their 50s rose by nearly half in the decade 1999–2010. Greenland, Lithuania, Japan, and Hungary have the highest rates of suicide. Around 75% of suicides occur in the developing world. The countries with the greatest absolute numbers of suicides are China and India, partly due to their large population size, accounting for over half the total. In China, suicide is the 5th leading cause of death.

Sex and gender

Globally , death by suicide occurs about 1.8 times more often in males than females. In the Western world, males die three to four times more often by means of suicide than do females. This difference is even more pronounced in those over the age of 65, with tenfold more males than females dying by suicide. Suicide attempts and self-harm are between two and four times more frequent among females. Researchers have attributed the difference between suicide and attempted suicide among the sexes to males using more lethal means to end their lives. However, separating intentional suicide attempts from non-suicidal self-harm is not currently done in places like the United States when gathering statistics at the national level. China has one of the highest female suicide rates in the world and is the only country where it is higher than that of men (ratio of 0.9). In the

Age

In many countries, the rate of suicide is highest in the middle-aged or elderly. The absolute number of suicides, however, is greatest in those between 15 and 29 years old, due to the number of people in this age group. Worldwide, the average age of suicide is between age 30 and 49 for both men and women. This means that half of people who died by suicide were approximately age 40 or younger, and half were older. Suicidality is rare in children, but increases during the transition to adolescence. In the United States, the suicide death rate is greatest in Caucasian men older than 80 years, even though younger people more frequently attempt suicide. It is the second most common cause of death in adolescents and in young males is second only to accidental death. In young males in the developed world, it is the cause of nearly 30% of mortality. In the developing world rates are similar, but it makes up a smaller proportion of overall deaths due to higher rates of death from other types of trauma. In South-East Asia, in contrast to other areas of the world, deaths from suicide occur at a greater rate in young females than elderly females.

, a person who died by suicide without the approval of the state was denied the honors of a normal burial. The person would be buried alone, on the outskirts of the city, without a headstone or marker. However, it was deemed to be an acceptable method to deal with military defeat. In Ancient Rome, while suicide was initially permitted, it was later deemed a crime against the state due to its economic costs. Aristotle condemned all forms of suicide while Plato was ambivalent. In Rome, some reasons for suicide included volunteering death in a

as the work of the Devil. In the Middle Ages, the Church had drawn-out discussions as to when the desire for martyrdom was suicidal, as in the case of martyrs of Córdoba. Despite these disputes and occasional official rulings, Catholic doctrine was not entirely settled on the subject of suicide until the later 17th century. A criminal ordinance issued by Louis XIV of France in 1670 was extremely severe, even for the times: the dead person's body was drawn through the streets, face down, and then hung or thrown on a garbage heap. Additionally, all of the person's property was confiscated. Attitudes towards suicide slowly began to shift during the Renaissance.

) toward suicide and brought a more modern perspective to the issue. David Hume denied that suicide was a crime as it affected no one and was potentially to the advantage of the individual. In his 1777 ''Essays on Suicide and the Immortality of the Soul'' he rhetorically asked, "Why should I prolong a miserable existence, because of some frivolous advantage which the public may perhaps receive from me?" Hume's analysis was criticized by philosopher Philip Reed as being "uncharacteristically (for him) bad", since Hume took an unusually narrow conception of duty and his conclusion depended upon the suicide producing no harm to others – including causing no grief, feelings of guilt, or emotional pain to any surviving friends and family – which is almost never the case. A shift in public opinion at large can also be discerned; '' The Times'' in 1786 initiated a spirited debate on the motion "Is suicide an act of courage?". By the 19th century, the act of suicide had shifted from being viewed as caused by sin to being caused by insanity in Europe. Although suicide remained illegal during this period, it increasingly became the target of satirical comments, such as the
Gilbert and Sullivan Gilbert and Sullivan was a Victorian era, Victorian-era theatrical partnership of the dramatist W. S. Gilbert (1836–1911) and the composer Arthur Sullivan (1842–1900), who jointly created fourteen comic operas between 1871 and 1896, of which ...
comic opera '' The Mikado'', which satirized the idea of executing someone who had already killed himself. By 1879, English law began to distinguish between suicide and homicide, although suicide still resulted in forfeiture of estate. In 1882, the deceased were permitted daylight burial in England and by the middle of the 20th century, suicide had become legal in much of the Western world. The term ''suicide'' first emerged shortly before 1700 to replace expressions on self-death which were often characterized as a form of self-murder in the West.


Social and culture


Legislation

No country in Europe currently considers suicide or attempted suicide to be a crime. It was, however, in most Western European countries from the Middle Ages until at least the 19th century. The Netherlands was the first country to legalize both physician-assisted suicide and euthanasia, which took effect in 2002, although only doctors are allowed to assist in either of them, and have to follow a protocol prescribed by Dutch law. If such protocol is not followed, it is an offence punishable by law. In Germany, active euthanasia is illegal and anyone present during suicide may be prosecuted for failure to render aid in an emergency. Switzerland has taken steps to legalize assisted suicide for the chronically mentally ill. The high court in Lausanne, Switzerland, in a 2006 ruling, granted an anonymous individual with longstanding psychiatric difficulties the right to end his own life. England and Wales decriminalized suicide via the Suicide Act 1961 and the Republic of Ireland in 1993. The word "commit" was used in reference to its being illegal, but many organisations have stopped it because of the negative connotation. In the United States, suicide is not illegal, but may be associated with penalties for those who attempt it. Physician-assisted suicide is legal in the state of Washington for people with terminal diseases. In Oregon, people with terminal diseases may request medications to help end their life. Canadians who have attempted suicide may be barred from entering the United States. U.S. laws allow border guards to deny access to people who have a mental illness, including those with previous suicide attempts. In Australia, suicide is not a crime. However, it is a crime to counsel, incite, or

another in attempting to die by suicide, and the law explicitly allows any person to use "such force as may reasonably be necessary" to prevent another from taking their own life. The Northern Territory of Australia briefly had legal physician-assisted suicide from 1996 to 1997. In India, suicide was illegal until 2014, and surviving family members used to face legal difficulties. It remains a criminal offense in most Muslim-majority nations.


Religious views


Christianity

Most forms of Christianity consider suicide sinful, based mainly on the writings of influential Christian thinkers of the Middle Ages, such as
St. Augustine Augustine of Hippo ( , ; la, Aurelius Augustinus Hipponensis; 13 November 354 – 28 August 430), also known as Saint Augustine, was a theologian and philosopher of Berber origin and the bishop of Hippo Regius in Numidia, Roman North Afri ...
and St. Thomas Aquinas, but suicide was not considered a sin under the Byzantine Christian code of Justinian, for instance. In Catholic and Orthodox doctrine, suicide is considered to be murder, violating the

"Thou shalt not kill," and historically neither church would even hold a burial service for a member that died by suicide, deeming it an act that condemned the person to hell, since they died in a state of mortal sin. The basic idea being that life is a gift given by God which should not be spurned, and that suicide is against the "natural order" and thus interferes with God's master plan for the world. However, it is believed that mental illness or grave fear of suffering diminishes the responsibility of the one completing suicide.


Judaism

Judaism focuses on the importance of valuing this life, and as such, suicide is tantamount to denying God's goodness in the world. Despite this, under extreme circumstances when there has seemed no choice but to either be killed or forced to betray their religion, there are several accounts of Jews having died by suicide, either individually or in groups (see Holocaust, Masada, First French persecution of the Jews and York Castle for examples), and as a grim reminder there is even a prayer in the Jewish liturgy for "when the knife is at the throat", for those dying "to sanctify God's Name" (see Martyrdom). These acts have received mixed responses by Jewish authorities, regarded by some as examples of heroic martyrdom, while others state that it was wrong for them to take their own lives in anticipation of martyrdom.


Islam

Islamic religious views are against suicide. The Quran forbids it by stating "do not kill or destroy yourself". The hadiths also state individual suicide to be unlawful and a sin. Stigma is often associated with suicide in Islamic countries.


Hinduism and Jainism

In Hinduism, suicide is generally disdained and is considered equally sinful as murdering another in contemporary Hindu society. Hindu Scriptures state that one who dies by suicide will become part of the spirit world, wandering earth until the time one would have otherwise died, had one not taken one's own life. However, Hinduism accepts a man's right to end one's life through the non-violent practice of fasting to death, termed '' Prayopavesa''; but ''Prayopavesa'' is strictly restricted to people who have no desire or ambition left, and no responsibilities remaining in this life. Jainism has a similar practice named '' Santhara''. Sati, or self-immolation by widows, is a rare and illegal practice in Hindu society.

According to Norbert Richard Adami, this ethic exists due to the case that solidarity within the community is much more important to Ainu culture than it is to the Western world.


Philosophy

A number of questions are raised within the philosophy of suicide, including what constitutes suicide, whether or not suicide can be a rational choice, and the moral permissibility of suicide. Arguments as to acceptability of suicide in moral or social terms range from the position that the act is inherently immoral and unacceptable under any circumstances, to a regard for suicide as a sacrosanct right of anyone who believes they have rationally and conscientiously come to the decision to end their own lives, even if they are young and healthy. Opponents to suicide include philosophers such as
Augustine of Hippo Augustine of Hippo ( , ; la, Aurelius Augustinus Hipponensis; 13 November 354 – 28 August 430), also known as Saint Augustine, was a theologian and philosopher of Berber origin and the bishop of Hippo Regius in Numidia, Roman North Af ...

– Mill's focus on the importance of liberty and autonomy meant that he rejected choices which would prevent a person from making future autonomous decisions. Others view suicide as a legitimate matter of personal choice. Supporters of this position maintain that no one should be forced to suffer against their will, particularly from conditions such as incurable disease, mental illness, and old age, with no possibility of improvement. They reject the belief that suicide is always irrational, arguing instead that it can be a valid last resort for those enduring major pain or trauma. A stronger stance would argue that people should be allowed to autonomously choose to die regardless of whether they are suffering. Notable supporters of this school of thought include Scottish empiricist David Hume, who accepted suicide so long as it did not harm or violate a duty to God, other people, or the self, and American bioethicist Jacob Appel.

Internet searches for information on suicide return webpages that 10–30% of the time encourage or facilitate suicide attempts. There is some concern that such sites may push those predisposed over the edge. Some people form suicide pacts online, either with pre-existing friends or people they have recently encountered in chat rooms or message boards. The Internet, however, may also help prevent suicide by providing a social group for those who are isolated.
