Well - no kidding. You see this in every protracted war that doesn’t have a clear objective - inevitably, soldiers plus time minus a plan leads to murdering The Others. Vietnam, the Balkans, WW1 & 2 - every war where you mix invaders and civilians over a long period of time leads to genocide. Soldiers without a plan will turn to killing whoever isn’t like them - quickly. One of the many abominations that the black hearted gangster ghoul needs to answer for.
Except it was part of the plan right from the start.
That’s true. Rolling crematoriums to incinerate military and political leadership. A specific plan on precisely how many people would have be to murdered to cow the rest into submission. The Russians seem particularly given to this type of casual industrialized death.
