I loved this season. As a serial killer who is selfish, Joe was needed to be faced in front of justice way earlier. But since things has been accumulating into a godforsaken mess, he deserves everything in the end.
There's no pity for him. Throughout 50 episodes we know he blames people based on how he was brought up in his childhood to his adolescence.
In the end, he still blames everyone else, "you"
