I'll admit that at this point this line of thinking is still a reach.
However, I am not equating empathy with hate.
I am predicting that hate will be the product of empathy, suffering, and honor.
Kaladin cares for, empathizes, and relates to these parshendi. Lets say that next these parshendi arrive at Kholinar and Alethi lighteyes kill them. Yet again Kaladin finds people he cares for being killed by Lighteyes. Insert Odium's influence on the parshendi while kaladin has aligned himself with this group. Where does that leave Kaladin but in a position where both Honor & Hatred would drive him to take action against the Alethi lighteyes. Do we genuinely believe Kaladin's hatred for lighteyes is past him? I Will Protect Even Those I Hate, So Long As It Is Right. The dude still hates lighteyes and what they have done to the world. In the situation with Moash, protecting Elhokar was what was right. But in this situation with the parshendi, what will Kaladin determine is right?
But perhaps it doesn't go this way. Perhaps his parshendi friends don't die but instead are consumed by odium and changed. Again people Kaladin cares for are destroyed. What emotions arise? Hate for Odium?
In either the question I want to find the answer to is, Is it possible for Honor & Hatred to be aligned.
Ultimately, my favorite idea is that Kaladin's story arc will develop to the point where he realizes that Lirin was right after all. You cannot kill to protect. perhaps this leads him to abandon Syl. Perhaps this ideal in a nutshell is why the recreance happened.
Without a doubt Brandon will prove all my careful consideration and theorizing wrong in the most exceptional way possible, but it sure is fun to think about.
