"I don’t think it’s at all easy to do an ongoing series with a full-fledged villain as the protagonist. You wind up either having to put them in situations where what they’re going is essentially heroic, or they need to lose all the time. And neither really serves the character well over the long haul." Well, it's working for Thanos. And the ones Magneto had were really good. Not to mention how hard it can be these days to say who's hero and villain in the Marvel U.
