I’ve always believed that violence can play a role in a moral life and a moral society. The world is much more violent that we think. There have been six times in the twentieth century that over a million people have been massacred. The Turks killed a million Armenians, Joseph Stalin killed millions of Russians, the Japanese killed millions in their rampage through the orient, Adolph Hitler killed millions, Pol Pot killed a million Cambodians, and the Chinese killed millions of their own people. It would be immoral not to oppose such horrible actions. However, that said, there is a quote by Nietszche appropriate here - “When opposing monsters take care that you don’t become a monster yourself, and if you gaze long enough into the abyss, the abyss will gaze back into you.” I think I got that quote close to right. The first part might be off, but the part about the abyss is accurate.
