I went for Suffering. I can be greedy and yet promote world peace (if you kill all my customers, who buys my stuff?). I can raise the undead and have them [a href=http://www.avernum.com/avernum3/index.html]run a lighthouse[/a]. But how could I possibly be sympathetic if my motivation is to hurt people?
(Note - that's not my modus operandi. A surgeon hurts people, especially in the days before anaesthetic. I'm talking about someone who does things specifically to hurt people.)
Oh, and Vengeance is on there twice.
Just for reference, probably the most important villain I've ever created (and no, I won't divulge more details) is motivated by good intentions, believing their actions to be for the greater good. It does swell into genocidal hatred, but the villain with perfectly reasonable motivations is always difficult to reason with.
