We do not do exactly to thieves or kidnappers as they have done to others, so why should we murder a murderer? I think that if we were to apply this principle in the case of murderers, we would have to apply it to all crimes. When thinking about it that way, it sounds very implausible. I also believe that human life is invaluable. However, I don’t agree that a murderer forfeits his right to life entirely when he murders another person because I do not believe such a thing to be possible. Everyone has a right to life regardless of their actions, and by encouraging the use of the death penalty, we are encouraging people to put a value on human life based on one's actions
