Kajune, the Mark corrupts its bearer. Yes, Lucifer always disliked humanity, but he'd never have betrayed his father and siblings by doing what he did, if not for the Mark.

KillRoy231, there is no redemption for what Crowley has done over the centuries. Remember the souls Sam saw in Hell? Remember how they were being tortured? As "the king", Crowley could have put a stop to that. But he didn't. His rule was so tyrannical that a demon actually committed suicide, because death was preferable to living in the Hell he made. He protected child abusers, killed babies, and who knows what else. I'd prefer redemption for him as well, but it's simply not possible at this point. Knife to the throat (or curing him, I suppose) is the only alternative.
