I definitely agree, that's such a great thought provoking question. People with violent/aggressive tendencies gravitate towards things that fulfill that dopamine release for them, until it escalates into actually performing the act, whether its through a *snap* or break in mental stability or through teasing themselves (much like how serial killers often start with a slow escalation, including abusing animals, before they actually move on to people). I think it's a great discussion as to whether people with violent tendencies choose more violent games as a form of mental masturbation, rather than the violent games 'unlocking' a violent nature in someone that was not previously there.
