Envy is one of the Seven Deadly Sins, and it is a form of resentment directed at other people's success and achievement. Rather than lovingly rejoice in another person's happiness, envy acts bitterly and seeks to bring the person down. Envy is often brought up from a fear that another person's goodness takes away from one's own. Its associated demon is Leviathan and its corresponding virtue is Kindess or Love.
