Execution refers to the legal process of carrying out a death sentence on an individual convicted of a serious crime, typically murder. This practice is a controversial aspect of the criminal justice system, with debates surrounding its morality, effectiveness as a deterrent, and the potential for wrongful convictions. Different methods of execution exist, including lethal injection, electrocution, and hanging. Each method has its own legal and ethical implications, and the use of the death penalty varies significantly across different countries and states, reflecting diverse cultural and legal perspectives on justice and punishment.
