Greed is not all bad.

At least when greed is described as the desire to have something better than what may be being lived right now.

Greed is bad when no environmental safety is taken or considered, and when the safety and/or health considerations of human beings as a whole are ignored.

Sharing and caring is much better. In the end, I think that if we each asked ourselves,

"If everyone did what I am doing right now, or am about to do, what would the world be like?"

If the outcome is good for everyone including the environment then it is a wonderful thing.
If the outcome hurts others and/or the environment it is not a good thing.
