Against Hitler Clones

My least favorite villain type is actually one of the most common: Hitler clones.  Genocidal madmen, who only want to purify their species/the universe by either removing one group or only preserving one.  The best example being Voldemort - evil to the core and born to kill, he hated muggleborns because his mother was a witch who died after raping his father.  And it's his father's fault that he ran away when he realized what she had done, of course.  A little depth does wonders with these people.  Take, for instance, Galbatorix, from the Inheritance Cycle.  He's certainly a Hitler clone - he eliminates all of the Dragon Riders, which necessitates the takeover of a large portion of the continent.  His future conquests revolve around maintaining his rule, rather than conquering for the sake of conquering.  As well, he has a good reason for hating the Dragon Riders - they sent him on the mission that killed his dragon, and with the mental disturbance that accompanied the event, it's not all that illogical to blame them.  Really, he's the best of the Hitler clones - he's got more personality than yet another Genocide Machine.  But aside from the rare few like him, and the rare few like the Daleks, who have an interesting appearance, good weapons, and a real threat beyond being evil, the Hitler clone is a sad, sad pack of villainy.  Abschied!
