OK. Let's bring it home. Do you think any of these people you seem to feel are only angry with "evil", would be willing to see just "evil" punished, but the humans through which that "evil" was perpetuated given a comfortable and pleasurable existence for Eternity?
C'mon, you know the answer. We humans want our vengeance against other humans.... period. We would never consider only "evil" being punished, and not the people like Hitler and Jack the Ripper through whom the "evil" was enacted, getting the full measure of punishment.
Yet this is exactly what the Bible says was done for you and me.
