The Ruthless trait bugs me.
Don't cultist souls end up as playthings of their "Gods"?
Destroying them is a mercy compared to that.
So selling them to the Sirens is a triple win. A mercy for the cultists, weakening the Four by denying them souls, and gaining psytech that is extremely valuable to our survival, and the safety of our souls.
What's so horrible about that?
As for bombing our cities, it would be sheer insanity not to. I would like THEM to withstand our wildlife (such as the berserker fungus), rampaging Alphas, and multiple daemonic incursions without resorting to such.
And for these acts we get called ruthless and willing to do anything for victory?!
We did those for survival.
Fuck those judgemental asses.
