To greed, all nature is insufficient.

Avarice (noun) : extreme greed for wealth or material gain.

Avarice, one of the seven deadly sins, is etymologically related to a desire to gain and withhold wealth and possessions. Whereas greed is etymologically related to hunger and insatiable appetite.

Anything I craved, I took,
Vain was what they had called me,
All for wanting more than they could ever imagine.
Ravenous, always hungry - yet insatiable,
In all of my glory, I laughed at them,
Crowns atop my head, I would have it all,
Even if it buried me alive.
