Alright Healing Factor, you and I are going to have to have a talk. Deadpool and Lobo can regenerate limbs. Wolverine can't. Lobo's an alien so it would make sense that he could still move and think (Or do what passes for 'thinking' with Lobo) without vital organs. Logan is human and last I checked we needed things like a functioning and intact nervous system. So with all this considered, shouldn't being ripped in half prevent Wolverine from moving, talking or doing anything that isn't at least passing out from sheer pain? Not to mention dying because, let's face it, 'Healing' just isn't going to cut it here.
