That is a commonly-held belief here in the USA, including many in my family with whom I've had debates. Here's the thing that makes no sense to me: if a person really believes 1) the criminal must "repent" before he dies otherwise he will be tortured by God for all eternity, and 2) if he does "repent" before he dies, then he will be safe and blissful for all eternity, then killing the criminal and cutting his life short is the cruelest thing you could ever possibly do to him. After all, the criminal is more likely to "repent" if you give him 40 years instead of just a few years. So I don't see how people who believe in eternal damnation can reconcile wanting to send a criminal to his "eternal torment" rather than giving him every single possible second to "repent". And before anyone says, "Well, they deserved it!", what possible crime could warrant even one hour of torture, let alone an eternity?
