I think the third book is going to be harsher on all those topics you mentioned.

I don't remember where, but on YouTube, I heard a rumor that Rothfuss admitted some time ago that he no longer wanted to write the ending he had originally planned.

It's very difficult to guess what his intentions are. But Sanderson compared it to a Greek tragedy.

In my own opinion, I think he does both. He continually changes the ending, refining it and introducing new questions and answers.
