I want to believe you that the Night Lords hate chaos, but we only followed one warband of nightlords.

We also saw the Bleeding Eyes and how warp touched they are. Shocking to Talos, but all of the Bleeding Eyes are corrupted to the point of mutilation.

We also have an interesting conversation between Cryian and Variel when Cyrian makes a comment about how warp touched their reclaimed ship (I forgot its name) from the Red Corsairs is. Some of its walls became living flesh. However Variel commented the Night Lords old ship, Covenant of Blood, was probably just as warp touched, and Cyrian didn't notice because he never went into most of the slave inhabited quarters.

I wish the Night Lords are more renegade than traitor, but I need to see more of them than one war band to make a decision.

Edit: IDK how to make a spoiler tag, so spoilers for the night lord trilogy. I just realized something Cyrian would actually know the Covenant of Blood wasn't as warp touched cuz it was him, not Uzas, who was murdering the slaves. Cyrian would in fact know that their old ship wasn't warp touched, but he could not bring that up to Variel.
