when you have the dark side, it can lead to greed in what you want because
someone WANTED something.. be it land, money, power, women, food, anything. I know that in some cases it was essential, but more often than not conflicts begin because someone doesn't have enough of something. And no one seemed to want to share.
Do you think that greed is the main source of problems on Earth? Some say money is, but that itself is the greed for more money..
