For the few psychopaths out there these violent games are just good practice.
So what is the answer?
Lock up the psychopaths. Most of the recent crop of nutters have long records of frequent interactions with police and shrinks. Lots of people, including their parents, have been not surprised by their actions, that means lots of people had the ability to stop them.
Untold millions and millions of people, all over the world, play violent video games like the GTA franchise, among numerous others. Of these, maybe a handful commit a seriously violent crime. If they’re anything like the DC Navy Yard shooter (who liked these games, we’re told), they were already bat s—t crazy to begin with. Tough to see causation in this case.
As a college student in the late 60s I worked in a mental institution. This was before they opened the doors and let them all out. There was a reason for those places then. And there is a reason now.
There is a crying need for psychos to be re instituted.
You are correct in says that they most players of these games are reasonably sane.
