There’s a concept in psychology called ego-syntonic vs. ego-dystonic. It refers to whether a person’s dysfunctional traits are in harmony with their self-identity (ego-syntonic) or in conflict with it (ego-dystonic).
When dysfunction is ego-syntonic, it can be more damaging to others than to the person themselves because they don’t see anything wrong with their behavior and feel no need to change.
