The bad guys got guns, so the good guys got guns.
The bad guys got bigger guns, so the good guys got bigger guns.
They lived in fear and arrogance and prayed to a mythical god for answers because knowing there was a plan would make sense of the senseless.
And they sorted everyone into victims and perpetrators because it was easier than looking in the mirror and stating the only plausible explanation:
"I AM TO BLAME.
I think in terms of us and them instead of brothers and sisters. I think I am more important than my fellow man. As long as I value myself, my people, and my things above everyone else's, there will be no peace."
They all armed themselves and invited their own destruction instead of loving each other so that all would thrive.
They were a foolish lot and the earth sighed in relief when they were all gone.
