"Darth Vader is the biggest Space Asshole ever, Bigger than Xenu, Cylons, Q, The Borg, and Zorak combined! I mean the guy starts a dictatorship, abuses his pregnant wife, kills children, cuts off his own son's hand, chokes people With His Mind, holds his daughters planet hostage for information, then blows it up anyway.
