Who says a particular behavior is evil? You go talk to jengis khan about good and evil in the thirteenth century from the mongol point of view. The perception thing is hard to get past, isn't it? From the perspective of someone who grew up in what the post war history books always called the great liberal democracies, the western democracies, you have concentration camps that are being used as genicide factory assembly lines. It's pretty much staked out where you are on the good evil side of the divide pretty clearly. For example, strategic bombing. There's always been an implication that the people that are being bombed somehow deserve it.
