Do you remember what the main cause of people turning ugly? I remember the prison experiment have to do with power and people playing authority. I'll never forget the guy in the shades. This is related to philosophy and Plato's ring of Gyges. If you had power, and you could get away with it, would you? Socrates in the Dialogue says it was never about what people do in power, but what people ought to do, and it depends on the condition on one's soul whether they will be corruptible. Looking at Marcus Aurelius as an example of uncorruptable power. However, his death led to his son's rise and there went the empire.
