If Fredo was exiled you guys think there is no chance he would try to kill Mike and take over? He's DUMB but he could still get lucky. There's not much of a chance he would do that but why leave any chance?
What if Fredo got so angry while he was exiled he talked to the FBI?
Neither of those scenarios would pan out. Sure, Fredo may have been angry at his lowly standing in the Family, but he wasn't hateful towards his family.
