Interesting perspective, and it's hard to disagree with the idea that there are people who are more outliers than some others on either end, which is just a natural result of any distribution, though I think another angle to this topic is how "good" and "bad" are always relative. Throughout human history, somebody who is regarded as a visionary, saint and savior by their own in-group might well be regarded as the biggest evil by another group of humans. Some simple examples would be somebody like Columbus or Genghis Khan. Those are extreme cases of course, but the same applies on various scales.
