From Dexter season 2 episode 7:

Angel: “Kill one man you’re a murderer. Kill thousands a conqueror. Kill them all and you’re a god”

Dexter: “To tell you the truth I don’t know what my alter ego had in mind when he wrote that crap, I just pulled it from various blogs on the Internet”

What, Dexter don’t listen to Megadeth?!?

(What do you mean that’s not from Dave Mustaine? Jean who?)
