The general consensus by everyone important is that violent videogames make people violent, correct? It's seems like a sound theory right? Well isn't it much more likely that violent people play violent videogames instead? Think about it, instead of sating your insane thirst for blood again and leaving more evidence, you play a violent videogame. Killing fake people as a normal person wouldn't make you more aggressive, it doesn't make sense, but an insane person killing fake people might have thoughts, or ideas, they might want to kill more. Mull this over, argue, I'll be back.
