Narcissists have very little ability to empathize with others; this lack of empathy is a hallmark sign of narcissism. Narcissists tend to be selfish and self-involved and are usually unable to understand what other people are feeling. They expect others to think and feel the same as they do and seldom give any thought to how others feel. They are also rarely apologetic, remorseful, or guilty.

Some narcissists also lack an understanding of the nature of feelings. They don't understand how their feelings occur. They think their feelings are caused by someone or something outside of themselves. They don't realize that their feelings are caused by their own biochemistry, thoughts, and interpretations. In a nutshell, narcissists always think you cause their feelings—especially the negative ones. They conclude that because you didn't follow their plan or because you made them feel vulnerable, you are to blame.

This lack of empathy makes true relationships and emotional connection with narcissists difficult or impossible. They just don't notice what anyone else is feeling.
