Seeing violence should indeed make you less violent unless you're a psychopath or trained to commit violence like modern soldiers are. This is a fun doco about most WW1-WW2 soldiers being unable to kill in combat, only 2% shot to kill, being psychopaths, and 10-20% shot in the direction of the enemy. http://youtu.be/2vlGR7S2wcI http://youtu.be/2vlGR7S2wcI Modern training makes 95% of soldiers killers. The training consists of simulating combat as realistically as possible and turning it into a routine. Amount matters there. Can realistic videogames give people some level of calm in a combat situation, which would allow them to kill better? Perhaps the military has some studies. Is it related to being the aggressor in shooting rampages and gang violence? Perhaps weakly.
