Mythology and History
Like Greed, Envy is characterized by an insatiable desire; they differ, however, for two main reasons. First, greed is largely associated with material goods, where as envy may apply more generally. Second, those who commit the sin of envy resent that another person has something they perceive themselves as lacking, and wish the other person to be deprived of it. Dante defined this as "a desire to deprive other men of theirs."
