My employer told me i am the nicest person she has ever known, and she is not calibrated to give those kinds of compliments. She is extremely direct and offends people as a result, but is well meaning and one of the hardest working people I've ever known. I admire her. I'm not often offended by people which helps to cut down on hurting them, although I am aware of times I have hurt people. It is not on purpose, and I don't process anger that way. As the matter-of-fact I have a difficult time processing anger because I analyze the cause and effects of it to the point that I understand why each person acted as they did and so I'm not angry about in the same way I'm not angry if it snows to much. It can be frustrating, but it isn't personal. Very few interactions between people have enough comprehension of the person to even rate as personal.
It is possible for there to be people who do not deliberately hurt others. For this to occur on a sincere, deep, honest level, it implies the person has the ability to respect and accept whomever they meet. It is that ability to respect people who are different, including those who do hurt people on purpose, that is the opposite of narcissism. The best way I know to be deeply kind is to let go of judgment and realize that harsh judgments are the result of pain and not truth. Looking deeper provides comprehension that makes judgment irrelevant.
