Re: Naruto 621
I believe both Batman and Wolverine have killed people several times though. In Batman's case it was due either from being pinned in a situation where he had no choice left, or going up against somebody way out of his league (Darkseid comes to mind) where the use killing force was essential just to have a chance. Wolverine is more of a feral rage kind of guy.
I also personally like heroes that have no problem killing, as long as the general populace of the comic/manga don't perceive them as heroes, but rather the rogue vigilantes they are. There's also something to be said for heroes who abstain from doing so for ethical reasons however. Whether that be a self imposed moral code or the belief that needless killing would eventually rob themselves of their own humanity, I give a certain respect for such characters given the right situations.
