Narcissists always try to make others look bad. They take pleasure in humiliating, belittling, criticising and condemning their targets. They alleviate their self esteem by making others feel small. In order for them to appear 'high' in status, they need to lower the status of others. They are pathetic people, who can't boast their own self esteem in a healthy manner, they have to resort to bullying behaviour to make themselves feel better.
