Sure you do. You act like an asshole most of the time and you have rationalized the people you do that to deserved it. That's a prime example of not abandoning the concept of good and evil even when you violate it.I don't rationalize any of my behavior because I don't have to.
And not everyone prefers good over evil and not to the same degree because good and evil are subjective
As for the rest, no one does evil for the sake of evil. They do evil for the sake of their own good.
