Evil people (who have malice in their hearts from jealousy) live to murder (both emotionally, others self-esteem; as well as their bodies!) good people, who have love in their hearts, live to love (to increase another’s self esteem, like the Lubavitcher Rebbe and the few great men and women who leave their selfish side for their selfless side) and the rest of us don’t really know why we live!
