He's a great character, but that doesn't change the fact that he has always looked upon Rogue as a child who just didn't "get it". He was always arrogant and condescending towards her, even in their break up issues!
And it should be noted that Rogue, while actually raised by a terrorist, forged her own path as a young teenager and has never gone back to that way of thinking. Magneto has gone back and forth, never seeming to settle on one theology, even though he's a grown man!
And please stop being patronising and telling me to read this or read that issue. I have read them, thanks. I recall that in X-men 45, Gambit offered her the opportunity to adsorb him, I think his words were "become me" so that she could see for herself what he had done. Rogue refused. I hardly call an offer like that "spitting in her face". When she left him to die in Antarctica, he forgive her without a second thought! I don't see Magneto ever forgiving such a betrayal.
They are a screwed up couple, no doubt, but nowhere near as screwed up as Rogue and Magneto.
