"Greed is known by many things. It is also known as avarice, cupidity, or covetousness! It is the inordinate desire to possess wealth, goods, or objects of abstract value with the intention to keep it for one's self. It is applied to a markedly high desire for and pursuit of wealth, status, and power. And does it harm you? No! It gives you power! It gives you strength! Far beyond that of any mortal could ever hope to comprehend! With power you are untouchable."
