Those are merely hypothesis, and almost every study concluded that “ A specific variant of the MAOA gene (VNTR 2R MAOA) was a risk factor of violent delinquency, but only when the boys suffered some other stress, such as family issues, low popularity and failing school.”.
Predispositions exist (still a hypothesis however Genetic Predispositions occur often) and anything can be a trigger. It's how some people who smoke weed might go down a darker path and weed being that trigger point. This applies to pretty much anything.
Cultural and education are the real culprit here. A well educated boy from a good family in a good school (good doesn’t mean rich or expensive, to be clear) with good friends won’t be violent just because he’s playing CoD and had a specific gene.
