Death Penalty

I want you to argue for a way the death penalty is wrong. I need 5 full pages, 6 sources (3 for your side and 3 against), with no paraphrasing or summary, proper MLA citation, proper MLA format, no 1st or 2nd person, and correct spelling and grammar. When writing your paper, keep in mind that moral and ethical laws and rules should have to apply to all people, in all situations, in all places, at all times.  In fact, we need moral and ethical laws and rules for human society to function and exist.  However, there are many contradictions.  For example, if not killing people is morally/ethically good, then is killing in wartime acceptable, is killing in self-defense acceptable, is the death penalty acceptable? Also, be careful of moral relativism, the belief that everyone should have their own subjective personal views of what is moral or immoral or ethical and unethical. The question I want argued is: why is something good or bad, right or wrong, moral or immoral, or ethical or unethical? If you are going to cite religious texts, quote from a variety of them.
