DETERRANCE
One of the death penalty's biggest advantages is deterrence, causing people to not want to commit violent and serious crimes because they know the punishment that would soon be given to them. John McAdams, a professor of political science, states "If we execute murderers and there is in fact no deterrent effect, we have killed a bunch of murderers. If we fail to execute murderers, and doing so would in fact have deterred other murders, we have allowed the killing of a bunch of innocent victims. I would much rather risk the former. This, to me, is not a tough call." McAdams is stating that rather them not killing murderers, and not deterring other murderer, rather than killing them and deterring the soon to be murderers, we are saving lives of innocent people. To make this effective, we must enforce this punishment soon after the criminal is confirmed guilty, just as if a child was instantly burned after putting his hand in a stove. If the penalty is given faster, it is proven to be more effective.
