Reading through the answers to this question on Hell it looks like the people commenting on the answers have a better grasp of the sources behind the subject than the people who answered.
This is not so good.
For one thing, the question should be closed or edited since the answer looked for reflects a doctrine. But if we're going to attempt to answer it, we need to do so with the Bible or other authoritative texts.
I think it's a good question. But what needs to be defined in the question is not what is meant by punishment and revenge, but what is meant by Hell!
