In that aspect its greed, ego and power getting in the way. Until people eliminate greed we will always have that problem. I'm talking about people like John Wayne Gacy, Ted Bundy, people like that. Thats why I suggested analyzing them and figuring out what exactly caused them to commit murder etc... Until you know exactly what is causing this to happen, you can't come up with a solution, you can only fix the small problems. Its like cutting your hand off and trying to use a bandage to fix it.
