There is one main feature that sets sociopaths apart from the rest of us. That one thing can be expressed in one word: conscience. Simply put, a sociopath feels no guilt. Because of this, he’s freed up to do virtually anything without having to pay any internal price for it. A sociopath can say or do anything she wants and not feel bad the next day, or ever.
Along with a lack of guilt comes a profound lack of empathy. For the sociopath, other people’s feelings are meaningless because she has no ability to feel them. In fact, sociopaths don’t actually feel anything the way the rest of us do. Their emotions operate under a very different system, which usually revolves around controlling others.
If the sociopath succeeds in controlling you, he may actually feel some warmth for you. The flip side of that coin is that if he fails at controlling you, he will despise you. He uses underhanded means to get his way, and if that doesn’t work, he’ll bully. If that fails, he will retaliate.
