IMHO, "evil" has everything to do with intent. I have an Nsis who is truly evil in my opinion because her hurtful actions are behaviors are intended to hurt others. Ns are fully aware of the difference between right and wrong. They just are so self-centered that they don't give a thought to others. Similarly, psychopaths are aware of right and wrong but they have no conscience. They are fully aware that the other person will be hurt by their actions....they simply don't care. Other people and their feelings are simply not on their radar. The same is true for many Ns. Their only concern is their feelings and pain, not anyone else's. That's why if you ever get into an argument with an N and try to explain that something they did or said really hurt your feelings, the conversation will instantaneously revert to how they feel. They cannot focus on anyone but themselves. They think the world should only be aware of their feelings, wants, desires, etc. No one else matters but them.
So for me, evil is all about the intention and motivation. Behaviors exhibited by "evil" people are usually malicious, mean-spirited and cruel. Evil people know their actions will hurt others because they are meant to. Evil people take great pleasure in exacting pain from others. They desperately want to see other people hurt.
Unfortunately, we all, at one time or another, do or say something to hurt another person. But the difference is the intention. Most of us never willfully do things to hurt others. Evil people do.
Just my two cents.
