Were you tempted to have Kaladin be taken by Odium?
Yes, I was tempted.
What is it the held you back from doing that?
Kaladin, if I were going to do it, I would have done it with Dalinar. The reason being that Kaladin as a theme represents his triumph over the darker parts of his mind. And Dalinar represents that too, but he also represents in some ways, succumbing to those. Like those are both themes for Dalinar, and for Kaladin it just would not ever have worked--I don't think--reasonably well. And beyond that, Kaladin is not scary as a villain, because Kaladin's strength comes from the people he's trying to protect. Kaladin's really scary to face when he thinks you're going after somebody he's trying to keep safe, that is when Kaladin is dangerous. Or as you saw in Rhythm of War, when you've gone too far, right? But Kaladin as an overarching villain, I don't think would be scary. Dalinar would be; Dalinar would be terrifying in that situation, but I don't think it would just add very much. If I were going to have had one of them, it would have been Dalinar.
