I am murderous and sad about the ambiguously open nature of the ending, but I will still recommend it to anyone and everyone because that is what you do after ORV happened to you.
Cale: I will set up my friends and family to bear the hero titles because I don't want it. Everyone else: Okay but. If all the heroes look up to and listen to you, what do you think that makes you?
Cale has sabotaged himself at every turn but I'm dead certain he'd do it all again if he regressed because he doesn't have it in him to just let everyone suffer.
