"Don't be a goddamn hypocrite. You sit there and point your big ass sword at me and call me a monster when all you useless shitstains need to do is look in the mirror. What you all fail to realize is that I'm nothing more than a shadow cast by the light that shines out of the world's collective asshole. Yeah, I'm a monster, but you were the ones who made me who I am." -Naruto U.
