I agree, Huntress IS badass I dunno if she's crazy though. She just sits on the moral line between guys like Punisher and Batman. She doesn't necessarily go out of her way to kill every thug she sees, but if they're complete scum, she doesn't really have a problem with "accidentally" shooting them. I mean, what's crazier? Devoting yourself to only killing or only not-killing, or judging on the spot what is necessary for the situation?
Then again, pretty much every super hero is a little unhinged in their own special little way, so I suppose she is nuts. :P
