I've done some hunting but there's something about the Thrill I don't understand.
We know that the Thrill isn't genetic but instead has to do with the location of Nergaoul. That's probably recursive; Alethela was designated to train soldiers, so Nergaoul got to do his thing, so the Alethi liked to fight more.
I understand Kaladin is immune to the thrill:
but I'm not clear on why. His immunity seems to extend to his squires, none of whom display the affects of the Thrill so far as we can tell. Seems to me that if you were to ask Kaladin "do you feel the Thrill?" he'd be like "what?" Is it a function of Windrunning? Being Radiant doesn't seem to be mutually exclusive from feeling the Thrill and frankly I don't know why it would be. The Unmade's aura effects seem to behave differently (Ashertmarn's temptation is highly localized and intense, Moelach's deathrattles are widespread but inconsistent, and Re-Shephir's presence could be felt by some but not by others). Also, despite the Nergaoul taking over Sadeas' army, Adolin doesn't seem to feel the Thrill at all at Theylan Field, despite having admitted in WoK that he does feel it. He misses like the first half of the battle, sure, but doesn't feel it or seem to notice that its missing.
I could keep rambling about weirdness that I keep noticing about the Thrill (Szeth, for example, also doesn't seem to feel it) but the bottom line is there seems to be something I'm missing regarding how it works and who feels it and who doesn't.
Also, yes this is my first post. Been lurking for a while though.
