Executions refer to the process of carrying out a death sentence imposed by a legal authority. This practice is often used as a punishment for serious crimes, such as murder or treason. Different methods of execution exist, including lethal injection, electrocution, hanging, and firing squad, depending on the laws of the jurisdiction. The use of executions is a controversial topic, with debates surrounding their morality, effectiveness as a deterrent, and potential for wrongful convictions. Some countries have abolished the death penalty altogether, while others continue to implement it as part of their criminal justice system.
