I thought that the reactions to Sadeas' murder were really interesting, especially since we know that Adolin is just standing there, watching all of it. On one hand, we have everybody agreeing that Sadeas' death was for the best, which makes total sense. Yeah, Sadeas was a strategic genius, but he would've been trying to pry Dalinar from power every chance he got.
But on the flip side, we have Dalinar mourning the Sadeas that he used to know. Not only is Sadeas' murder going to cause division in the already divided Alethi armies, but Dalinar obviously disgusted by the murder.
There's no way that he'll ever accept Sadeas' death as anything other than a brutal, unlawful murder, which is going to cause problems when he discovers who the murderer is (which I'm guessing will occur in this book, fingers crossed.) And I'm sure that Ialai isn't going to fade into the background, we know that she was just as politically savvy as Sadeas. Maybe she'll frame Dalinar, causing problems for his efforts to unify? If Adolin tries to justify his actions, maybe he'll consider murdering her (or others who are causing problems and distracting from the Everstorm and upcoming Desolations)?
So is Adolin going to feel justified because everyone agreed that Sadeas' death was for the best? Or is he going to suffer because the man he respects most, his father, is mourning his old friend and assumes that he was murdered brutally and wrongly? Will Adolin kill again, even if it's a good idea? Not only will Dalinar be upset about Adolin's decision, but Kaladin is definitely going to be against it, especially with that whole 'protecting those I hate' deal. And what about the Skybreakers? Is this something that they'll get involved in? I'm not sure how Shallan, Renarin, or the others will react, but I'm psyched to see how this turns out.
