What Joab did not and could not know was that it was ego, and the ego of a king is just like the ego of anyone else. It is a social infection, entering each person as a psychological virus that is passed on by their parents’ egos and other social stimuli. It is born of negativity—of not being good enough thoughts of not having enough, of fear, and worry of failure. Because of its insecure nature, the ego loves to dominate and control others. It’s control or be controlled.
