Needless death is what gives rise to war. And wars are fought to blot out the evil. The expectation of war, is that justice will be served. But war is not justice. Innocent people die in war.
War is anarchy.
It is the opposite of law and order. War happens because people don't follow the Laws, or because they argue about what the laws are. War is the result of disputes. As far as I'm concerned, there is only One Right, as there is only One G-d. If everyone followed G-d's Laws, there would be no disputes, and there would be no wars.
