Moral Event Horizon: Every Chaos worshipper has already crossed the horizon at one point. However, a few examples stand out:
- Gorgone Locke's Cold-Blooded Torture of Eisenhorn
- Cherubael's threat to Eisenhorn and Bequin at the climax of Xenos firmly establishes him as someone utterly evil:
I will break every bone in your body and rape that girl by your side. And break every bone in her body. Then I will drag your jiggling carcasses down to the cathedral and burn out your agony centres while I wait for the bombardment to flatten this place
- Pontius Glaw trying to kill all of Eisenhorn's old friends.
- Inquisitor Osma's attack on Essene.
