" A recent paper reviewed the findings from all available studies of the relationship between empathy and aggression. The results are summarized in the title: “The (Non)Relation between Empathy and Aggression: Surprising Results from a Meta-Analysis.” They report that only about 1 percent of the variation in aggression is accounted for by lack of empathy. This means that if you want to predict how aggressive a person is, and you have access to an enormous amount of information about that person, including psychiatric interviews, pen-and-paper tests, criminal records, and brain scans, the last thing you would bother to look at would be measures of the person’s empathy.

Being high in empathy doesn’t make one a good person, and being low in empathy doesn’t make one a bad person. "
