It actually goes surprisingly in depth discussing "what happened" (assuming you're thinking of what I think you're thinking about). It's the kind of thing that seems like it might be resolved a little too tidily at first, and then several (or perhaps dozens) of chapters later, it comes back in a big way.
That describes a lot of plot points in this story, come to think of it. As of Ch. 55 there's still a lot of moral grey area and most character dynamics are continuing to evolve in interesting ways.
So (unless we're thinking of very different things) he re-evaluates it multiple times throughout the story.
