What makes a man?

What makes so many of the world leaders turn into cold-blooded heartless killers? I wonder how their wives and children feel knowing that their husband or father is ordering the gruesome deaths of innocent civilians. I wish that one day the kids would sit their father down and say, “If you love us like you say you do, please stop because they are innocent children just like us.” I wish that their wives will ask them how they would feel if another man were to rape and torture them. Maybe the solution to end the evil lies in their homes.
