It's (greed) a relentless desire to achieve something regardless of ethics

I think this is the key point about greed. It's like people try fill a void that never fills. However, when one is driven by ambition, there comes a point at which one can stop because one no longer needs to continue pursuing something because one has already obtained it, one has already fulfilled it, one has already achieved one's goal.

Really good post 👏👏👏
