Well the whole story is quite horrible, but yes when poeple paint video games and gamers as the scapegoats for every crime imaginable its insults us and makes us overly defensive. Violence has been around since life began and believe it or not its actually getting better (as in there is less of it) , people thousand or two thousand years ago considered ritualistic human sacrifice a common thing. A man's life at certain situation cost less than that of a bull, slavery was a norm, should i mention gladiators who were killed for the sole amusement of the public? Its not untill a couple centuries ago that big changes started happening , and when such despicable act takes place it isnt the norm or noone would find it shocking. The way i see it video games help relieve stress and aggression a person accumulates during the day ,not building it up, i'm fairly certain that without a dose of Doom and GTA in my life i would go batshit crazy and go on a killing spree IRL ,thankfully to the wonders of technology i can instead kill a bunch of pixels.
Hamsters and Rangers everywhere rejoice!
