"additionally, what comprises an inter-group clash, is likely somewhat subjective"
True enough - but some discrepancy.
The point I was making was that the overwhelming taking of life in any society is caused by wars for political and monetary gain facilitated by 'the great and the good' - totally beyond our control and most certainly nothing to do with a inherited inclination to kill.
What does worry me is the glorification and minimising of life-taking that is being sold to our kids as entertainment.
Come back in a generation or so's time and you may well have a point.
Yes - I know our parents said the exactly same about the comics we read and the films we saw, but I suggest that the sophisticated detachment that comes with today's offerings of violence is really something else - bring back Tom Mix, I say!!
