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 serious offenses like murder. While many nations have abolished it, some still practice capital punishment for certain crimes. There are moral, practical, and legal arguments both for and against its use. Supporters argue it deters serious crimes and ensures justice, while opponents argue it is an unreliable and inhumane violation of a basic right to life. The morality of the practice is widely debated around issues of fairness, error, and the sanctity of human life.
