Saying a person is bad even if they did nothing to you, only out a warped social notion isn't okay at all. Would you do that on a lesser scale? Would you say somebody was the worst person in your town if you heard rumors he sold heroin and shot people you don't even know as acquaintances? No, I'd rather put people who wronged me on the list. Plus, it'd make a more interesting topic than "Totalitarian regimes I never was a part of are the worst!". Well, unless you're over 60 years old or a terrorist attack victim. Then it's fair game. As a student of history, I have to say you couldn't be any more wrong. In order to judge present actions as wrong, we must first have guidelines for judging what is wrong and what is right. Obviously we get these from analyzing instances of right and wrong from the past. If, according to your logic, we cannot judge historical figures like Hitler, Stalin, and Mao as being wrong simply because they haven't done anything wrong to us or anyone we know, that would mean current leaders around the world that commit genocide would have to be deemed in the right. I would like you to tell that to Rwandan refugees or Kurdish families massacred under Saddam Hussein's rule. We have to judge the actions of those who lived in the past based on the time period they were in and how they interacted with others during their lifespan. There can be any number of interpretations of an individual's actions, but saying they can't be judged because they haven't committed any wrong to you or someone you know is completely and utterly ridiculous.
