Yep. I disagree with the idea that playing violent video games generally leads to violent behavior, but in this case it does seem to have played a role.
In fact, I believe Bryer was the ideological leader. He's the one who would get a little too excited while playing violent video games and excitedly said, "can you imagine if this were real?" Based on a multitude of things we've heard about Bryer, I believe he had homicidal and suicidal fantasies for a long time. (A point I have made many times now, I might add. And I have to say I now feel vindicated vs those who have been claiming they were just a couple of basically nice boys who made a few mistakes. Sorry, I just had to say that because I found those ongoing claims to be so incredibly frustrating.)
It's absolutely clear to me that Bryer was a complete lunatic and the ideological leader. Kam may have been the logistical leader, who decided what they were going to do next, but it was Bryer who had the deviant fantasies and somehow got Kam on board.
The one thing that puzzles me is how Bryer was able to convince Kam to commit suicide. He must have had a very persuasive argument, because I doubt Kam was suicidal.
moo.
