Capital punishment, or the death penalty, is the execution of a convicted criminal by the State as punishment for crimes known as capital crimes or capital offences. The word "capital" is derived from the Latin "capitalis," which means "concerning the head"; therefore, to be subjected to capital punishment means to figuratively lose one's head.

Historically, the execution of criminals and political opponents was used by nearly all societies - both to punish crime and to suppress political dissent. Among democratic countries around the world, most European and Latin American states have abolished capital punishment while the United States, Guatemala, and most of the Caribbean as well as democracies in Asia and Africa retain it. Among nondemocratic countries, the use of the death penalty is common but not universal.

In most places that practice capital punishment today, the death penalty is reserved as a punishment for premeditated murder, espionage, treason, or as part of military justice. In some countries with a Muslim majority, sexual crimes, including adultery and sodomy, carry the death penalty, as do religious crimes such as apostasy, the formal renunciation of one's religion. In many retentionist countries drug trafficking is also a capital offense. In China human trafficking and serious cases of corruption are also punished by the death penalty. In militaries around the world courts-martial have imposed death sentences for offenses such as cowardice, desertion, insubordination, and mutiny [1].

Capital punishment is a contentious issue. Supporters of capital punishment argue that it deters crime, prevents recidivism, and is an appropriate punishment for the crime of murder. Opponents of capital punishment argue that it does not deter criminals more than life imprisonment, violates human rights, leads to executions of some who are wrongfully convicted, and discriminates against minorities and the poor.
