Yeah, which is where I was going with the whole "this just damages the character more since this kind of thing is what they're already notorious for."
I mean, superhero characters go nuts and have villain periods all the time. You just fix them and move on rather than go back and keep confusing the issue more by rewriting over rewrites over rewrites.
It's infinitely simpler to just have Kafka or Reed or Strange or whoever restore his mind and move on.
