The source of evil is desire, greed, and anger.

Greedy people are never satisfied that they have enough. They’re like sharks that spend their entire life hunting and consuming. All the oceans in the world can’t satisfy these eating machines.

Greed makes one want to get something he/she has not worked for

Sexual desire and anger shall not seduce you, and the dog of greed shall depart.

You can satiate a Man's hunger but never his greed!

There is no one who is completely evil as to lack some goodness in him.
