The imperfection of human being; we make mistakes and the emotional guilt developed amongst us to become more rational and civilized being. Our guilt in our past experience should not be avoided, but rather acknowledged it and do something to become a better you. Having a sympathy or compassion is a rare form of human being and usually it is one of the traits of a leader. We help people because of our guilt experiences, being compassionate with guilt driven will motivate people with a sense of togetherness and harmony. :)
