Capital punishment is needed in order to keep our society from becoming one filled with criminals.
In all states, murder is punishable by death. The death penalty is used to keep killers from entering our society to kill again. You may say there are alternatives to killing, such as life in prison. The average life sentence was commuted in six years and nine months in 1987. This says that for murder, a killer can be paroled after nine years, a sentence much less from the one prescribed.
