Why should a murder deserve to live?
well for starters because execution is permanent and can't be corrected in the event that you realize you were Wrong All Along and the ""murderer"" was actually innocent
tbh tho i always thought of it more like this: the murderer is too dangerous to be part of society, and why waste money keeping them in prison when we can just get rid of them? although I heard that the death sentence is more expensive than a life sentence, idk how though
because the time of prosecution attorneys and law enforcement is valuable and expensive. convincing a jury that someone deserves to be killed for their actions is not as easy as you may think. it can take years, and it's not over even once you "get" the death sentence. there are appeals, the possibility of new evidence. and law enforcement has to find very damning evidence in the first place, there has to be minimal doubt that they really did commit the crime, if you're going to resort to killing them. and if even then there are mistakes, then maybe this just isn't the right way to do things
