If you met a man, and he told you that he loved violence, you would think at best he was insane.
But every society that has ever existed has done so on a foundation of being able to produce sufficient violence to secure resources and protect it populace.
Some of these societies have been good, others bad, but the ones that were not prepared to do sufficient violence in defense of their resources and their way of life have ceased to exist.
Humans are, I think, by nature a fundamentally vioient animal. We are also a social animal, and out of a need to practice and also not kill or maim our valuable fellow humans, we play games of violence.
But always keep in mind - there is a difference between harmless and peaceful.
