Capital punishment, also known as the death penalty, is the execution of criminals convicted of capital crimes by the state. It has been used throughout history as punishment for offenses such as murder, treason, kidnapping, and witchcraft. While many nations have abolished it, some like the U.S. and Bangladesh still practice it for certain crimes. Proponents argue it deters crime and brings closure for victims, while opponents argue it violates human rights, is prone to error, and lacks deterrence based on evidence. Morally, there are debates around whether governments deserve to kill those they imprison given issues with racial bias and unequal treatment.
