When I go to movies that have various kinds of hideousness in them, I like to have my own fundamental difference from sadists and fascists and voyeurs and psychos and Bad People unambiguously confirmed and assured by those movies. I like to judge. I like to be allowed to root for Justice To Be Done without the slight squirmy suspicion (so prevalent and depressing in real moral life) that Justice probably wouldn’t be all that keen on certain parts of my character, either.
