If you are expecting realism from a game full of magic, monsters, hats that cut you in half, people that shoot lightning from their hands, turn into dragons and eat you than I don't know what else to say. Would it be great if he picked another organ each time? sure, would it be great if a ninja didn't use a headbutt? yeah, isn't it odd that he freezes their liver/stomach and smashes it without his hand leaving an entry/exit wound? yeah that's pretty bad too but still this is just a game not an anatomy class lol.
