Wait..I take all that back. Voldy's body must have had a bit of his soul. Otherwise he wouldn't have been alive after all 7 horcrxes were destroyed. So I guess his soul was divided into 8 parts. Unless..his bit of soul in Harry is still there and it was only his body that died in the duel. I do recall Harry rubbing that scar in the so-called epilogue. Who knows, maybe JKR left herself a loophole to bring Voldy back for another book or two. I'm really grasping at straws here aren't I.
