That's not entirely true. Like 4% of people are sociopaths with an inability to feel empathy for others or feel guilt for their actions. There really are evil people who know what they are doing is wrong and just don't care.
This is what I consider evil, and I think it's important to separate it from people who think what they are doing is ok. I.e. "Someone else would have done it anyways", a thief who steals from a bank because "they have insurance" or "they are rich assholes who don't deserve it", or a dictator who tries to do what he thinks is best for the country even though his policies are bad.
Tou keep saying that, but it doesn't mean what you think it means.
