Whoever was speculating above about potential redemption for Jimmy...
I don't see it.
That's the biggest contrast between Jimmy and Kim. She's weighted down by far more conscience than Jimmy ever has been, and her life has been a waking nightmare since Howard's death, whereas Jimmy not only brushed it off but prospered enormously--for a time--by embracing the dark side of the force.
In fact, to stick with the Star Wars analogy, Jimmy is definitely a "It's too late for me, son" kind of guy. There's no going back for him, even if there was an opportunity. It would require a humility that's totally inconsistent with his character's ego.
Jimmy's going down with the ship, just like Walter White.
So I predict.
