The saying "an eye for an eye" has been interpreted many different ways, including to excuse the intentions of revenge. Capital punishment is posted in the strength of this saying, meaning if you take a life, you don't deserve to keep your life. Yet states are wildly divided on whether to instate it or not. This informative book presents essays on the effectiveness of capital punishment as a deterrent to crime, examining the issue from differing points of view. It includes discussion of related topics such as: the death penalty as a form of terrorism control; the role of the death penalty in community protection, whether the death penalty actually saves lives.
