I can't believe that people are getting bent out of shape over Will Smith's remark about Herr Schickelgruber. I think it illustrates a major problem, a problem that may be inherent to the human condition or may be a cultural artifact of this particular place and time in our culture. To wit, we are raised believing in self-identified Evil. From the bad guy in every movie and fantasy novel to the opponent in every video game, there is this persistent belief that Evil will be easily identifiable because it will wear a black outifit, cackle maniacally, and announce itself as such.
The world don't work that way. As Mr. Smith attempted to point out, not even the most despicable characters in this planet's history thought of themselves as Evil. Nero never said "MWA-HA-HA!" when barbecueing dangerous subversives from Near-East mystery cults. Hitler never woke up and rubbed his hands together and thought "I think I'll be Eeeevil today!" The most heinous crimes perpetrated throughout the millenia have been perpetrated by people with clear consciences because they were doing what they were doing For The Common Good.
Watch out for that. When evil comes, it won't be easily identifiable, with a hunched back and a crazed glint in its eye; it will be nicely dressed, sound reasonable, and have a great team of policy wonks and spin doctors to explain exactly why you need to climb into the cattle car, please.
