Whenever people ask me for advice, I simply apply what I've learned
from Dr. Phil: I yell at them and tell them how stupid and lazy they
are and how all of their problems are their fault.

I don't think his roommate have ever mentioned the killer playing video games...like, he just sat there staring off into space or typing.

I think people are moving the focus from the actual cause of the massacre, Video games don't kill people, people kill people. And the only one we have to blame is the killer him self.
