Soldiers who have been through horribly violent experiences in war, may on the one hand, suffer severely from post traumatic stress syndrome and spend the remainder of their lives trying to forget these experiences. On the other hand, veterans can also feel that their experiences in wartime and their friendships during those times were the most real experiences of their lives. So the remainder of their lives may revolve around remembering those experiences. I do not condone violence or in any way suggest we should tolerate the level of violence in which we live. But it seems to me that honesty requires recognition that violence is a part of life.
Violence can bring life into bolder colors and give life an intensity that often seems missing.
Religion has always had an aspect of violence to it. A primary focus of Christianity is on an act of ritual torture and killing by crucifixion. In the origins of baptism, the idea was for a person to physically experience the sensation of drowning and then come back to life born anew. The scarring rituals of indigenous tribes recognize while growing up that the cutting of the bonds of childhood, like a chick breaking from the egg, is in part a violent act. Modern day versions of this are body piercing by young people and the stripes on a sergeant's sleeve.
