[Gorwingel]

I think most of those did recieve a shot a redemtion, I would hope Gollum and Boromir would get redemtion because their evil deeds were mostly the fault of the ring.
You could also maybe include orcs here, I don't know, because remember is says that deep in there hearts under all that evil, they really don't like there masters, because they were originally elves that were forced into doing that.
