Actually, I don't think that socipathy works that way, but it is true that socipaths don't have the conventional fears that most "normal" people have.
If you mean fight or flight response, I wouldn't call it fear. It is a biological trigger that makes one respond much faster than the rational mind can process. An instinct.
What I am talking about is that a lot of people have blocks, and those blocks they call fear. Sometimes it is the same mechanism as fight or flight and it akes them freeze in certain situations. Sometimes they use it to not to do something. Sometimes people overthink and worry a lot. I am guessing word worry is much beter description for something that sociopaths lack!
And a lot of worry comes fromthings that person has no control over. That is what I am talking about. I don't worry about things I have no control over, and change ones that I have instead of worrying about them. It is just you used word fear in your post, and I used it as well. There are different meanings to every word, sorry about that misunderstanding.
And that gives me an idea. I really should write the post about The Fear. I really like Hunter Thompsons writing, and I think he was on to something. Too bad they cut that monologue in The Rum Diary movie, because it summed up his views really well. I even think it is central to understanding his writing.
