answer:This subject has been debated to death on every Q+A site I can remember, while no I am not for capital punishment, you put one innocent person to death your no better than they are. BUT for true monsters such as Olsen(Canada)Dalmar(U.S) and sorry if I didn’t spelled their names right yeah they should be put down. As a deterrent, nope not at all people will still kill each other for whatever damn reason.
