Gregory's Serveras long as -sociopathic- humans are in power.
Most humans are not willing to kill for power.
But unfortunately when rule by violence (military) is still seen as legit (much less a huge industry), the few who are willing to kill for power -will- use violence to grab at this form of sick stunted power.
That never gets any mention in the for profit propaganda machines, nor in the other forms of education they desperately try to manipulate and control.
