I think I'd understand it better if Magneto hadn't gone completely nutso.

[Morph really wasn't the type to give a lecture, and they didn't have any words of wisdom, either. It was pretty obvious that what happened at Genosha had made Magneto snap, and they could even understand why Rogue chose to follow him... but the guy had been ready to completely wreck the planet. That was far above and beyond your typical bad-guy plot.]

... Magneto was awake, you know. Before whatever happened to the asteroid. I saw him fly right out of the jet.
