There's a lot of talk about Arthas getting a redemption arc with the recent cutscene. For obvious and spoiler reasons. I'm not -entirely- against it given the manipulation he went under thanks to Frostmourne but if his actions were 100% his own that makes things complicated. --

This is a very similar case for characters like Garrosh and Sylvanas. Garrosh did everything on his own with no corruption - unless they retcon Y'sharaj twisting his mind which I doubt. Then there's Sylvanas who has done everything on her own as far as we know. --

After the Third War Sylvanas basically broke free, broke any of the Scourge free and turned them on Arthas. Her actions in Classic to Wrath while grey were not too irredeemable and at least it was out of a just goal. But that goes down hill after Arthas is dealt with. --

She's no longer under anyone's control and her new reason for existing and "thriving" is to not go to Hell. Her goal of revenge turns into a goal of survival. And a very selfish one at that drives her to do very bad things. Far worse than what Arthas has ever done. --

Going back to Arthas, yes he did terrible deeds but most of them were under the influence of Frostmourne and the Helm which (spoilers) are now revealed to be linked to the Jailer. Sylvanas doesn't really have that excuse anymore which is why "redemption" doesn't feel right.

I think the problem that most people have is all of the things LEADING up to Frostmourne. I think that's the point no return ,but he had done a number of things call his morals into question before that (stratholme, the burning of the ships in the northrend expedition)
