My .02USD on the subject. The guy's getting what he deserves.
Correct me if I'm wrong, but:
1) Video games have been out since the 1960's or so, violent crimes have happened since the dawn of man. The dawn of man was eons before the 1960's.
2) If your 13-year-old kid is playing an M rated video game, and you don't like it. Ask yourself, how did the kid got the video game? And even if you didn't buy it for him, why is he still playing it?
3) When religion is involved, a common reason is to say it's wrong because it goes against God. Well, who in this world then guarantees the righteousness and sanity of your God**?
Having said that, think of the consequences before you act. If you don't like it, move along, nothing to see there. Don't make stupid statements saying, it's the root of all evil without proof. I have a couple of articles on the subject, if anybody wants to read them, I'll post some links.
Cheers.
** On this notice, I am a Roman Catholic. I choose not to talk about my religious practices because my beliefs are of no concern to the person next to me. I always ask myself the question, just like in Plato's dialog Euthyphro: "Is the pious pious because it is dear of the Gods, or is it dear of the Gods because it is pious?" That being a question that Socrates and Euthyphro left unanswered. Recommended read, by the way.
