@gungasnake,
There are NO CRIMES when One is at 'WAR'.
If I HAVE to 'exterminate' you (For, whatever reason).
I HAVE to 'exterminate' you.
I can't foresee any reason why I need 'exterminate', harm, or upset anyone or anything.
But, If there were - I would - Without concern for moral-guidelines, cultural-limitation or terms of sportsmanlike behaviour.
IF YOU (not shouting, emphasis) WERE RAPING, BEATING, TORTURING, etc, ME - HOUR BY HOUR - DAY BY DAY - OVER & OVER.
And my only escape was/were to extinguish the ENTIRE universe - In order for this to cease - UNIVERSE = BYE-BYE.
I'm not going to be (raped, tortured, maimed, etc) and overly consider how my actions are going to affect anyone else.
As for 'societal-wars' - They're all manufactured - As is your 'bondage' to your 'prescribed'-'alliance/s'
