We Who Wrestle with God - Jordan B. Peterson

I just finished listening to this in audiobook form. It was fascinating to me, an endless discussion of major stories in the Bible from a perspective that combines Psychology, Science, History and many ideas unique to the author.
This is not a Bible commentary, although it contains lots of commentary. It is not a theology, although it discusses many theological issues. It is more a big picture application of human psychology and sociology, and an exploration of good vs evil, order vs chaos.
He spends a lot of time on Cain and his multiple stages of falling away from God. I never understood why God would protect Cain from being killed, when he himself had committed the first murder. Peterson puts all the pieces together in a way I have not seen before.
I do not know if a book like this belongs in Logos. If it were, I would want it in my library simply to have it in searchable form.
You would not take this book to Sunday School. It does contain a few (just a few) words that might be offensive to some.
I have a few questions …
Have you read this?
If so, do you think it belongs in Logos?
How would you categorize it?
