I will suggest that it might be appropriate to describe yourself as a "sociopath" which I believe currently has no clinical definition but colloquially tends to be understood as negative and somewhat similar to, though less than, "psychopath". Folks here are not likely to accept some colloquial self-determined definition of a term like "psychopath" when it has a clear clinical definition.
I have two very challenging children, one of whom is not empathetic, tends towards narcissism and so on. Like you, he stays out of trouble by making judicious choices concerning the longer range consequences of his actions which I spent a lot of time educating him about (in other words, I did not appeal to some sense of morally "right" behavior, which he lacks, instead I focused on developing a perspective of enlightened self-interest). He shares many traits with his father, my ex husband, whom I found quite difficult to deal with. But I get along extremely well with my oldest son. He was raised very differently from his father. He has a very similar nature to his father but the nurture part varied considerably and the difference in outcome has been substantial.
EDIT: Which is to say I agree with a point I feel you are trying to make that having X trait in no way guarantees Y outcome. Most people who know him superficially describe my oldest son as "very polite and respectful" or "a very nice young man". Others who have had to deal with him more than just superficially tend to find him pretty crazy-making.
Yes, exactly: Clear as mud is very socially acceptable for most "normal" people (not necessarily on HN where people will pedantically argue every definition with you). Say "sociopath" and then if someone asks what you mean by that have a clear description of what you are trying to convey (basically define it yourself). It is a malleable word, open to interpretation. It gets you a lot less shit from other people than using the word "psychopath". I know because it is a word I and my sons use in part for this very reason.
My remarks are intended to be a helpful suggestion, based on something that has worked for me. That's it.
