Fairly new to the Cosmere and just finished OB. My understanding may be limited, but I joined because of this thread. I believed, when I read the book, and nothing in this thread has changed my mind, that We = Odium and Dalinar and you = Evi. To me, it just fit. As other had mentioned, BS started the long game back in TWoK and Dalinar's story being closely related to The Thrill. We find out, during this sequence, that Odium is feeding The Thrill to Dalinar and has been, for a while. We learn that Odium pushed Dalinar to kill his wife, through The Thrill. We know that Odium believes he is aware of how much pain Dalinar is under and is supremely confident that his plan will work.
To me, it was obvious that Odium had seen the future, way back then, and "knew" that he had to get Dalinar to kill his wife because the guilt he would feel, years later, would be compounded with all the other things he had done while under the influence of The Thrill, and that would push Dalinar to his side, when he (Odium) offered to take responsibility for all those acts. Evi saying "I forgive you" could not had been anticipated, much the way (as also previously pointed out) that Renarin couldn't see Jasnah sparing him.
So, the only thing against that I can come up with, that makes sense, on the surface is, if Odium "knew" Dalinar was going to join him because of the pain that The Thrill and killing Evi has caused him (Dalinar), why/how did Dalinar not give the pain to Odium before Evi forgave him. If this all rotates around Evi, then Dalinar should have not been able to fight Odium until he was forgiven. EXCEPT, if we are going with the idea that Odium saw the future before Dalinar killed his wife, then he may not have known that Dalinar would seek out the Nightwatcher and lose his memories, allowing him to grow in a way that Odium may not have been able to foresee.
I liken this to playing chess with my best friend. He hated playing against me because every so often, I'd do something so stupid it would up-end his overall strategy and give me the victory. I'm a very mediocre player, and he was pretty good. Dalinar going to the Nightwatcher may be that one move, in the game that Odium didn't anticipate so didn't bother to check on, ect. Since Dalinar was still experiencing The Thrill after that visit, Odium may not have been aware of the changes.
Almost everything above has been mentioned above, at this point I'm just adding that I, too, believe that. The WOB that is quote, referring to a RAFO, imo, doesn't cloud the issue any more than it's already clouded. I also believe that this was purposely put in. As I've heard other's say, BS is a very specific writer and it seems like, to me, in this particular instance, he's purposefully playing the pronoun game so we specifically have to ask and since he doesn't give us an answer by the end of the book, it's going to be bigger than we expected...
