Death by violence, death by cold, death by starvation - they are the normal endings of the stately creatures of the wilderness. The sentimentalists who prattle about the peaceful life of nature do not realize its utter mercilessness.
If we know how much passive violence we perpetrate against one another, we will understand why there is so much physical violence plaguing societies and the world.
There is nothing wrong with violence in itself. In any particular case, whether violence is good or bad depends on how it is used and the purpose for which it is used.
