Strange you mention Death Note since I'm listening to Maximum The Hormone right now.
OT, L of course.
Kira was an asshole. Light had a twisted and corrupt view of the world. One human does not have the right to take that power in his hands and use it as he pleases.
He killed people without even so much as a second thought. The only reason he kept people around was so he could use them enough before they became a threat to him, then he'd kill them.
Besides, L kicked ass and was probably one of the best comic book characters ever.
