Actually most countries don't have or use the death penalty insanity:

Of the 194 independent states that are UN members or have UN observer status:

* 42 (22%) maintain the death penalty in both law and practice.
* 97 (50%) have abolished it.
* 7 (4%) retain it for crimes committed in exceptional circumstances (such as in time of war).
* 48 (25%) permit its use for ordinary crimes, but have not used it for at least 10 years and are believed to have a policy or established practice of not carrying out executions, or it is under a moratorium.
