Invidia - Envy

Like greed, Envy (Latin, invidia) may be characterized by an insatiable desire; they differ, however, for two main reasons:  First, greed is largely associated with material goods, whereas 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.
In Dante's Purgatory, the punishment for the envious is to have their eyes sewn shut with wire because they have gained sinful pleasure from seeing others brought low. Aquinas described envy as "sorrow for another's good".
