BREAKING: Shooting at Conn. Elementary School

I think getting serotonin highs by killing people in video games is not good.

With violence I think you get an adrenaline rush. With most other addictive behaviors that don't involve substance abuse, it's a dopamine high.

What's really disturbing to me is that so much of what is promoted in our society is addictive by design, and that's where the big money is made in psychology. That, IMO, is why treating/preventing mental illness isn't a priority. 

Anyway, I agree with you that's it's problematic.

You're contradicting yourself. Above you said that people blame other things instead of addressing the problem. Millions of people play violent video games and realize it's just a game and form of entertainment. Playing grand theft auto doesn't make people want to go out and kill, if it does then there is some other deep rooted problem going on and they'd do it regardless.
