Actually...you might want to take back the rock/music thing because many a veteran rocker and those in the music industry have said 1) occultism had a lot to do with their music being produced and aimed at causing a reaction and mindset in listeners, 2) There are psychologists and people in curious positions in the music industry that have contributed to algorithms purposefully made to cause a specific reaction out of the listener. <br><br>Now there is the saying "you become what you behold and there are extreme occult/mind-control experiments, if not tortures, devised to alter the mindset. Much of it focuses on repetition of behavior; the stereotypical viewing something over and over we see in some films. The subtle form is viewing something over a lifetime, which typically only produces desensitization. Violence is harder to break the threshold into reality because it has immediate consequence or big negative. But we do see sex, drugs, gambling and consumerism and other behavior mimicked based on continued exposure to the point it's normalized behavior.<br><br>For very few, the mentally unwell for whatever reason find outlets in violence, but typically there are venues taken to satisfy any violent urge. I do believe domestic violence has increased, and narcissism, which typically indicates sociopathic tendencies in developed nations, and abuse victims typically stay quiet or there are missing pets....so no, videogames don't cause violence, they attract people already that way or filtering through it. Same as how pedophiles find fictional underage content to subdue their urges, if exposure to it did not lead to becoming hooked on it.
