Are you FOR or AGAINST death penalty?

Hello excellence7. I'm definitely against it. why? I don't think anyone has a wright to kill other people. I know that many people may say, does a killer deserve to live if he killed someone? The thing is.. if we understand that it's a crime to kill someone and we want to punish people doing this, how can we do this crime ourselves? It doesn't make difference that in our opinion he did something horrible, maybe in his opinion the one he killed did something horrible as well.
