Jealousy

A strong feeling of possessiveness, often caused by the possibility that something which belongs, or ought to belong, to one is about to be taken away. The word can be used in a positive sense (e.g., the jealousy of God), meaning a passionate commitment to something which rightly belongs to one. It can also be used in a negative sense (e.g., human jealousy), to mean a self-destructive human emotion similar to envy.
