At the listening party I went to, I got actual goosebumps and got choked up when we got to this one.
I actually do think it fits on the record. I think it's a very deliberate twist or pivot. I've never gotten the feeling the brothers do pointless inclusions, and I think the fact that this is ALMOST the last thing you hear on the album (not counting the bonus track really, it's bonus) is not a coincidence.
You've just been through Hell when you hear this for the first time. I think this song is right where it needs to be.
