Somebody I know is in hospital right now after shooting himself in the head playing Russian roulette. I know it's stupid, yes he's an idiot. He's on life support, it happened 5 days ago. It was a smith and Wesson revolver and it lodged into his head, about an inch from the top of his ear. Is there any chance of him surviving it? He had surgery and they removed the bullet fragments about 40 hours after he shot himself. Will he survive or not? If he does will he be his normal self? Or will he be a vegetable? How much chance is there that he will survive and be his normal self, maybe with a bit of brain damage but he will be the same? I'm not sure if the bullet touched his brain... Could it through that part of the skull or is the bone too strong? Any help would be appreciated and please don't hate or judge.
