"In fact the only one handed over to execution was Him and he was innocent. "
Jesus wasn't innocent - he was GUILTY. It's just that we, today in our Christian society, don't agree that what he was guilty of was a crime. But the fact is, back in his day, and in his community, and under the government he lived under at that time, according to their laws, he was guilty.
Example: Suppose the city of Arcola had a law against stepping on the cracks of a sidewalk. Even if you think it's a stupid law, even if you're not hurting anyone, if the law says don't do it and you go ahead and you step on a crack, then you have committed a crime, and you are GUILTY.
That's one of the problems with being on a jury. I, personally, don't think there's anything wrong with smoking pot (as long as you're not driving, that is). But, since there is a law against it, if I were on a jury, whether or not I thought the law was a just law, I would have to I would have to vote to convict a person who was caught smoking pot, whether I agreed he had done something "wrong" or not.
Bottom line: Jesus was guilty.
Re the death penalty, I don't believe we have the right to kill other people, no matter what evil deed they have done. I do, however, believe we have the obligation to remove such people from society. If they can't be rehabilitated (and most of the really bad criminals can't), then we need to keep them where they cannot harm other people, which means prison.
To me, it's not so much a matter of punishment (which is really nothing other than vengence and retalliation), but of prevention. Ideally, prison would be used to rehabilitate. But, when that can't occur, then we need to use prison to prevent a bad guy from committing more crimes.
