It’s a Jim Jones suicide cult ideology. The end of such is always a self destructive one once they go “all in”.
That is why the good people hesitate. To deal with such suicidal monsters one also has to make one’s face like ‘flint” and become hardened to the guilt trips that sort of enemy tries to throw at you. You have to make sure that yours is the true “righteous cause” before you go all in against these people and right now these people control nukes....that is what is making them very confident and stupidly reckless!
Jones would have a hay-day with all the sheep nowadays.
