'' carried its everyday meaning – a deliberate and premeditated (prior intent) killing of another motivated by ill will. Murder necessarily required that an appreciable time pass between the formation and execution of the intent to kill. The courts broadened the scope of murder by eliminating the requirement of actual premeditation and deliberation as well as true malice. All that was required for malice aforethought to exist is that the perpetrator act with one of the four states of mind that constitutes "malice". The four states of mind recognized as constituting "malice" are: Under state of mind (i), intent to kill, the ''deadly weapon rule'' applies. Thus, if the defendant intentionally uses a
deadly weapon A deadly weapon, sometimes dangerous weapon (although some jurisdictions differentiate between the two) or lethal weapon, is an item that can inflict mortal or great bodily harm. By statutory definition, certain items, especially firearms, are de ...
or instrument against the victim, such use authorizes a permissive inference of intent to kill. Examples of deadly weapons and instruments include but are not limited to guns, knives, deadly toxins or chemicals or gases and even vehicles when intentionally used to harm one or more victims. Under state of mind (iii), an "abandoned and malignant heart", the killing must result from the defendant's conduct involving a reckless indifference to human life and a conscious disregard of an unreasonable risk of death or serious bodily injury. In Australian jurisdictions, the unreasonable risk must amount to a foreseen probability of death (or grievous bodily harm in most states), as opposed to possibility.; but the common law has been modified in NSW: . Under state of mind (iv), the felony-murder doctrine, the felony committed must be an inherently dangerous felony, such as burglary, arson, rape, robbery or kidnapping. Importantly, the underlying felony ''cannot'' be a

such as assault, otherwise all criminal homicides would be murder as all are felonies. In Spanish criminal law, murder takes place when any of these requirements concur: Treachery (the use of means to avoid risk for the aggressor or to ensure that the crime goes unpunished), price or reward (financial gain) or viciousness (deliberately increasing the pain of the victim). After the last reform of the
Spanish Criminal Code The Criminal Code is a law that codifies most criminal offences in Spain. The Code is established by an organic law, the Organic Law 10/1995, of 23 November, of the Criminal Code (''Ley Orgánica 10/1995, de 23 de noviembre, del Código Penal' ...
, in force since July 1, 2015, another circumstance that turns homicide into murder is the desire to facilitate the commission of another crime or to prevent it from being discovered. As with most legal terms, the precise definition of murder varies between jurisdictions and is usually codified in some form of legislation. Even when the legal distinction between murder and manslaughter is clear, it is not unknown for a jury to find a murder defendant guilty of the lesser offense. The jury might sympathize with the defendant (e.g. in a
crime of passion A crime of passion (French: ''crime passionnel''), in popular usage, refers to a violent crime, especially homicide, in which the perpetrator commits the act against someone because of sudden strong impulse such as anger rather than as a premed ...
, or in the case of a bullied victim who kills their tormentor), and the jury may wish to protect the defendant from a sentence of life imprisonment or execution.


Degrees of murder

Some jurisdictions divide murder by degrees. The distinction between first- and second-degree murder exists, for example, in Canadian murder law and U.S. murder law. The most common division is between first- and second-degree murder. Generally, second-degree murder is common law murder, and first-degree is an aggravated form. The aggravating factors of first-degree murder depend on the jurisdiction, but may include a specific intent to kill, premeditation, or deliberation. In some, murders committed by acts such as

State laws in the United States vary as to definitions of "premeditation". In some states, premeditation may be construed as taking place mere seconds before the murder. Premeditated murder is one of the most serious forms of homicide, and is punished more severely than manslaughter or other types of homicide, often with a

An act such as murder is wrong or evil by its very nature, and it is the very nature of the act which does not require any specific detailing or definition in the law to consider murder a crime.

Depending on the circumstances, these may or may not be considered criminal offenses; they are often considered manslaughter. * Suicide does not constitute murder in most societies. Assisting a suicide, however, may be considered murder in some circumstances.

Since independence, death sentences for murder in such cases had always been commuted; the new act was intended "to eliminate all the terrible ritual of the

Unintentional

For a killing to be considered murder in nine out of fifty states in the US, there normally needs to be an element of intent. A defendant may argue that they took precautions not to kill, that the death could not have been anticipated, or was unavoidable. As a general rule,
manslaughter Manslaughter is a common law legal term for homicide considered by law as less culpable than murder. The distinction between murder and manslaughter is sometimes said to have first been made by the ancient Athenian lawmaker Draco in the 7th cen ...
constitutes reckless killing, but manslaughter also includes criminally negligent (i.e. grossly negligent) homicide. Unintentional killing that results from an involuntary action generally cannot constitute murder. After examining the evidence, a judge or jury (depending on the jurisdiction) would determine whether the killing was intentional or unintentional.

With advances in modern medicine, most countries have abandoned a fixed time period and test causation on the facts of the case.

In Islam

In Islam according to the Qur'an, one of the Islamic views on sin, greatest sins is to kill a human being who has committed no fault. "Do not take a ˹human˺ life—made sacred by Allah—except with ˹legal˺ right." "That is why We ordained for the Children of Israel that whoever takes a life—unless as a punishment for murder or mischief in the land—it will be as if they killed all of humanity; and whoever saves a life, it will be as if they saved all of humanity." "˹They are˺ those who do not invoke any other god besides Allah, nor take a ˹human˺ life—made sacred by Allah—except with ˹legal˺ right,1 nor commit fornication. And whoever does ˹any of˺ this will face the penalty."


Historical attitudes

The term ''assassin'' derives from Hashshashin, a militant Ismaili Shi'ite sect, active from the 8th to 14th centuries. This mystic secret society killed members of the Abbasid, Fatimid, Seljuq dynasty, Seljuq and Crusader elite for political and religious reasons. The Thuggee cult that plagued India was devoted to Kali, the goddess of death and destruction. According to some estimates the Thuggees murdered 1 million people between 1740 and 1840. The Aztecs believed that without regular offerings of blood the sun god Huitzilopochtli would withdraw his support for them and destroy the world as they knew it. According to Ross Hassig, author of ''Aztec Warfare'', "between 10,000 and 80,400 persons" were human sacrifice, sacrificed in the 1487 re-consecration of the Great Pyramid of Tenochtitlan. Japanese samurai had the Kiri-sute gomen, right to strike with their sword at anyone of a Caste, lower class who compromised their honour.


Slavery

Southern slave codes did make willful killing of a slavery in the United States, slave illegal in most cases. For example, the 1860 Mississippi case of ''Oliver v. State'' charged the defendant with murdering his own slave. In 1811, the wealthy white planter Arthur William Hodge, Arthur Hodge was hanged for murdering several of his slaves on his plantation in the British Virgin Islands, Virgin Islands.


Honor killings in Corsica

In Corsica, feud, vendetta was a social code that required Corsicans to kill anyone who wronged their family honor. Between 1821 and 1852, no fewer than 4,300 murders were perpetrated in Corsica.


Incidence

The World Health Organization reported in October 2002 that a person is murdered every 60 seconds. An estimated 520,000 people were murdered in 2000 around the globe. Another study estimated the worldwide murder rate at 456,300 in 2010 with a 35% increase since 1990. Two-fifths of them were young people between the ages of 10 and 29 who were killed by other young people. Because murder is the least likely crime to go unreported, statistics of murder are seen as a bellwether of overall crime rates. List of countries by murder rate, Murder rates vary greatly among countries and societies around the world. In the Western world, murder rates in most countries have declined significantly during the 20th century and are now between 1 and 4 cases per 100,000 people per year. Latin America and the Caribbean, the region with the highest murder rate in the world, experienced more than 2.5 million murders between 2000 and 2017.


Murder rates by varies countries

Murder rates in jurisdictions such as Japan, Singapore, Hong Kong, Iceland, Switzerland, Italy, Spain and Germany are among the lowest in the world, around 0.3–1 cases per 100,000 people per year; the rate of the United States is among the highest of developed countries, around 4.5 in 2014, with rates in larger cities sometimes over 40 per 100,000. The top ten highest murder rates are in Honduras (91.6 per 100,000), El Salvador, Ivory Coast, Venezuela, Belize, Jamaica, U.S. Virgin Islands, Guatemala, Saint Kitts and Nevis and Zambia.

/small>). The following absolute murder counts per-country are not comparable because they are not adjusted by each country's total population. Nonetheless, they are included here for reference, with 2010 used as the base year (they may or may not include justifiable homicide, depending on the jurisdiction). There were 52,260 murders in Brazil, consecutively elevating the record set in 2009. Over half a million people were shot to death in Brazil between 1979 and 2003. 33,335 murder cases were registered across India, approximately 17,000 murders in Colombia (the murder rate was 38 per 100,000 people, in 2008 murders went down to 15,000), approximately 16,000 murders in South Africa, approximately 15,000 murders in the United States, approximately 26,000 murders in Mexico, about 8,000 murders committed in Russia, approximately 13,000 murders in Venezuela, approximately 4,000 murders in El Salvador, approximately 1,400 murders in Jamaica, approximately 550 murders in Canada and approximately 470 murders in Trinidad and Tobago. Pakistan reported 12,580 murders.


Murder in the United States

In the United States, 666,160 people were killed between 1960 and 1996. Approximately 90% of murders in the US are committed by males. Between 1976 and 2005, 23.5% of all murder victims and 64.8% of victims murdered by intimate partners were female. For women in the US, homicide is the leading cause of death in the workplace. Chapter 6, Responding to Workplace Violence and Staff Victimization. In the US, murder is the leading cause of death for African American males aged 15 to 34. Between 1976 and 2008, African Americans were victims of 329,825 homicides. In 2006, Federal Bureau of Investigation's Supplementary Homicide Report indicated that nearly half of the 14,990 murder victims that year were Black (7421). In the year 2007, there were 3,221 black victims and 3,587 white victims of non-negligent homicides. While 2,905 of the black victims were killed by a black offender, 2,918 of the white victims were killed by white offenders. There were 566 white victims of black offenders and 245 black victims of white offenders. The "white" category in the Uniform Crime Reports (UCR) includes non-black Hispanic and Latino Americans, Hispanics. Murder demographics are affected by the improvement of trauma care, which has resulted in reduced lethality of violent assaults – thus the murder rate may not necessarily indicate the overall level of social violence. Workplace homicide, which tripled during the 1980s, is the fastest growing category of murder in America. Development of murder rates over time in different countries is often used by both supporters and opponents of capital punishment and gun control. Using properly filtered data, it is possible to make the case for or against either of these issues. For example, one could look at murder rates in the United States from 1950 to 2000, and notice that those rates went up sharply shortly after a capital punishment in the United States, moratorium on death sentences was effectively imposed in the late 1960s. This fact has been used to argue that capital punishment serves as a deterrent and, as such, it is morally justified. Capital punishment opponents frequently counter that the United States has much higher murder rates than Canada and most European Union countries, although all those countries have abolished the death penalty. Overall, the global pattern is chaos theory, too complex, and on average, the influence of both these factors may not be significant and could be more social, economic, and cultural. Despite the immense improvements in forensics in the past few decades, the fraction of murders solved has decreased in the United States, from 90% in 1960 to 61% in 2007. Solved murder rates in major U.S. cities varied in 2007 from 36% in Boston, Massachusetts to 76% in San Jose, California, San Jose,

History of murder rates

According to scholar Pieter Spierenburg homicide rates per 100,000 in Europe have fallen over the centuries, from 35 per 100,000 in medieval times, to 20 in 1500 AD, 5 in 1700, to below two per 100,000 in 1900.Spierenburg, Pieter, ''A History of Murder: Personal Violence in Europe from the Middle Ages to the Present'', Polity, 2008.

"Rap Sheet Why is American history so murderous?"
by Jill Lepore New Yorker, November 9, 2009
In the United States, murder rates have been higher and have fluctuated. They fell below 2 per 100,000 by 1900, rose during the first half of the century, dropped in the years following World War II, and bottomed out at 4.0 in 1957 before rising again. The rate stayed in 9 to 10 range most of the period from 1972 to 1994, before falling to 5 in present times. The increase since 1957 would have been even greater if not for the significant improvements in medical techniques and emergency response times, which mean that more and more attempted homicide victims survive. According to one estimate, if the lethality levels of criminal assaults of 1964 still applied in 1993, the country would have seen the murder rate of around 26 per 100,000, almost triple the actually observed rate of 9.5 per 100,000. A similar, but less pronounced pattern has been seen in major European countries as well. The murder rate in the United Kingdom fell to 1 per 100,000 by the beginning of the 20th century and as low as 0.62 per 100,000 in 1960, and was at 1.28 per 100,000 . The murder rate in France (excluding Corsica) bottomed out after World War II at less than 0.4 per 100,000, quadrupling to 1.6 per 100,000 since then. The specific factors driving this dynamics in murder rates are complex and not universally agreed upon. Much of the raise in the U.S. murder rate during the first half of the 20th century is generally thought to be attributed to gang violence associated with Prohibition in the United States, Prohibition. Since most murders are committed by young males, the near simultaneous low in the murder rates of major developed countries circa 1960 can be attributed to low birth rates during the Great Depression and World War II. Causes of further moves are more controversial. Some of the more exotic factors claimed to affect murder rates include the availability of abortion and the likelihood of chronic exposure to lead poisoning#Nervous system, lead during childhood (due to the use of leaded paint in houses and tetraethyllead as a gasoline additive in internal combustion engines).


Investigation

The success rate of criminal investigations into murders (the clearance rate) tends to be relatively high for murder compared to other crimes, due to its seriousness. In the United States, the clearance rate was 62.6% in 2004.
