Murder is the unlawful killing, with malice aforethought, of another person, and generally this state of mind distinguishes murder from other forms of unlawful homicide (such as manslaughter). As the loss of a human being inflicts enormous grief upon the individuals close to the victim, and the commission of a murder is highly detrimental to the good order within society, most societies both present and in antiquity have considered it a most serious crime worthy of the harshest of punishment.
