i think hell get the surgery and be successful, if they dont and they make him die, theyre dumb becuz he was a good character in the story who can prolly be a character who can defeat a really powerful villain later in the series since he can open gates
i think of it as the sasuke cursed seal, " omg only 10% chance to live ( or w/e it was ) " and surprisingly he lives U.U
prolly the same thing here..
