It's... not uncommon for one or another of them to get taken over by a cosmic entity, go crazy, or just act like a total dick. Avengers sometimes do it too but usually it's explicitly the result of magic or technology or Wanda. But with Rogue the way her powers work, it's like she absorbs part of a person when she gets their powers, and if she gets too many or any of them are too strong it can be a problem. As far as I knew it wasn't happening anymore since she learned control but right now I'm really not ruling it out.
