But as the most evil, heinious, despicable, sinister Jedi to ever walk the surface of any planet, Vader is no. 1. Let's face it: A nazi-ish helmet, skull mask and all pitch black: They simply don't come more evil than that. And beside, he got the coolest tune. Luke doesn't even have his own tune, and there must be a reason for that :bleh:
