Is there a possible similarity between the kolas blood list and the thrill?

[Caleb]

This just occurred to me I wasn’t sure. Any thoughts?

[Noah]

I think the Koloss "bloodlust" comes primarily from the fact that their tribal organization is rather barbaric due to their lower intelligence, whereas the Thrill is a direct effect of Nergaoul the Unmade's presence. Nergaoul is part of Odium's Investiture, but I don't think we know much more about any Investiture-related side of the Koloss bloodlust... I'd recommend you to Nergaoul's page on the Coppermind and the Koloss Coppermind page
