It seems like such as clear cut example of how "bad people" think though. They always considered themselves justified in harming others.

Variations of "the golden rule" are common around the world. If you actively decide to treat others in a way that you don't want to be treated, then you've failed the most universal rule of being a decent person.

I fully understand thoughtless knee jerk behavior that is unethical, but taking your time and calming coming up with the idea that you are special and it's ok to harm others... it's just a bit strong on the cognitive dissonance.
