Well, while I agree with you that pretty much all of the executions of that attitude are terrible, the attitude in of itself isn't bad. Mostly because the executions all involve harems and rapepits and the like, while true 'I want to be in charge, and I will take it' irredeemable evil just isn't done unless the people you are taking from are even worse. I, for one, would also like to see a game where you are evil, fighting good, played absolutely straight, doing evil without hesitation or remorse, but only when it advances your overall goals, and occasionally for your own petty amusement.
