He should be dead within 30 seconds, the werewolf heart is about 2/3 the size of a humans, but in order to shrink, first it has to stop. In other words, he has a heart attack. All the internal organs are smaller so while he's having his heart attack he's having liver and kidney failure too, and if he stops screaming its not because the pain has dulled, his throat, gullet, and vocal cords are tearing and reforming. He literally can't make a sound. By now the pituitary gland is working overtime, flooding his body with endorphins to release some of the pain but that too is shut down. Anyone else would have died of shock long ago, but it won't. And that's the thing I find most remarkable. It drives him through the fire and keeps him alive, and even conscience, to endure every second. nothing like this could just evolve, is it the fingerprint of god? An imposable curse spread by tooth and claw victim, against victim, against victim, its so cruel... its perfect.
