The death penalty should NOT come back. No human being has the power to decide who lives and dies. What should happen is that life sentences should be just that, LIFE, they should die in prison.
if you use that philosophy then what gives one human the right to imprison another for their entire life? The decision is made by the culprit as soon as they decide to carry out an act such as this, theyve only got themselves to blame. Your only entitled the same rights of the victim, an eye for an eye and all that.
