It's just efficiency. The extremes of sexual debauchery and violence in games generally involve the solicitation of prostitutes and violence against non-combatants. Thus killing a prostitute after you've slept with her, easily exemplifies both vices into a single activity.
commented on Video games getting blamed for Navy Yard attack is misdirection and irresponsible of mainstream media
I propose the government start a "Games for Guns" program. As video games are obviously the greatest factor in the cause of gun violence, they should give people the opportunity to trade in their deplorably dangerous video games for harmless firearms. Because it is only by arming everyone with lethal weapons and removing virtual outlets for aggression, that we will finally put an end to all the senseless violence.
