Does greed have anything to do with fighting?  You'll find the answering by looking in the Bible in James 4:1-2, TLB  "What is causing the quarrels and fights among you? Isn't it because there is a whole army of evil desires within you? You want what you don't have, so you kill to get it. You long for what others have, and can't afford it, so you start a fight to take it away from them. And yet the reason you don't have what you want is that you don't ask God for it."

It's okay to have material things, isn't it? Look in the Bible in Luke 12:15 NIV  "Then [Jesus] said to them, "Watch out! Be on your guard against all kinds of greed; a man's life does not consist in the abundance of his possessions."

Is it true that the love of money leads to evil?  Check out the answer in the Bible in 1 Timothy 6:10, NIV.  "For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs."
