Violence for entertainment...

I'm reading a lot lately about removing violence from movies, video games and the like. Of course, a lot of movies are based on books. As a writer, I'd like to give my take on that.
In an ideal world, yes, of course we'd like to protect our kids from growing up in a culture that doesn't unilateraly condemn violence. Seeing violence in movies and video games, and there is a copious amount of it, at some point dulls our senses to the true effect of it. When we experience violence in our lives it is nothing short of traumatic. It can be and often is life-changing. It leaves many with disabling injuries and unfortunately lives are needlessly lost through unexpected and senseless violence.
Let's imagine for a few minutes that we woke up one day and there was no violence in movies, video games, on TV or in books. None. As the world acclimated to that utopia would violence cease to happen? Would all the kids who no longer saw violence as entertainment grow up to be peaceful, nonviolent adults? Some, maybe. All of them, no. Some of the kids who grew up in broken homes or had no family or someone who cared for them at all would still grow up mad at the world. Kids who grew up with parents who were drug addicts or were drug addicts themselves as kids would still kill for a fix. Kids that grow up to be violent more than likely didnt have XBoxes or Playstions or computers when they were kids. They couldnt afford them. They saw violence acted out on the stage of life. Their own life.
The problem isnt really taking violence out of movies and entertainment, it's taking violence out of life itself. It's taking mental illness, broken homes, broken families, drug addiction, desperation in life, out of life. It's like a cancer, you remove it from one place and it's back somewhere else, usually worse than before.
That begs the question, why are we entertained by violence? We dont want to experience it but we want to watch it happen to someone else. Are we all addicted to schadenfreude by nature? It sure looks that way. I mean, if you think about it, we are entertained by watching violence? I see it like this. We are not really entertained by violence per se. We are entertained by watching lives that are lived dangerously, out on the edge so to speak. We dont want to live our own lives dangerously and be caught in life-threatening predicaments, but we like to watch others do it. We like to watch good triumph over evil, we even like the scorn we feel when the good guys lose. We like stories that involve the things that inevitably happe in life, however tragic they may be. Then we like to go back to our own quiet and peaceful lives. We like to witness people living exciting, precarious lives without taking the risk ourselves. There is nothing wrong with being entertained like that. Those that create such stories are no more prone to violence than those who watch them. Tragic stories have been created since the creation of literature. Shakespeare, Chaucer, Dickens, Sir Arthur Conan Doyle, F. Scott Fitzgerald, all told classic stories that involved tragedy and death. And have been enjoyed for centuries by many people. By reading, watching, learning through stories that contain tragedy, death and violence we are exposed to these things from a distance. We see others perspectives on them and are influenced by them. It gives us something to use in forming our own view of the world. Violence in a movie or a book doesnt make the world more violent. It doesnt make people in the world more violent. The seed of that particular tragedy is planted somewhere else...
