My sights are too small. There's already no heaven or hell in the Death Note world right? so there's no real consequence outside of human law for using it, and even then that's only if you're an idiot or try and get noticed. I'd use it only for my personal use, I have nobody I hate but I know that can also change at any time. I have no grand scheme or problems with the universe as a whole. That said, I CAN be selfish and if an accidental heart-attack gets somebody out of my way or gets me somewhere i'll most likely take it.
