Alastor redemption theory.
Guys, Alastor gets redeemed soon, if you say I'm wrong just go ask him yourself... JK of course.
But I genuinely think the odds or much more in his favor then he, or even we, realize.
My evidence:
Sir. Pentious was placed in hell due to the deifying act of standing by while others were harmed. he knew damn well he could have helped, but he didn't. Weather it was from fear, cowardice, or just for his own well-being, he didn't act. That's his defying act; that's the reason he was placed into total damnation. But it might have been the reason he got out as well.
As, in the fight against Adam in season 1 episode 8, he fights alongside his friends, but in a moment of true selflessness, where it was eighter he could run off, or act: He chose to act.
In a true selfless act, he sacrificed himself for the survival of others. That action reedified his own defying act, which in return got him redeemed.
Now my true theory:
I strongly believe Alastor will be (Weather in the next season or at the end of the show.) redeemed, weather he chooses it or not.
With my evidence, sinners in hell have a defying trait that got them into hell, but if they truly do the opposite of what got them there, they can be redeemed weather they wanted to or not. So, I believe Alastor will face a situation where is requires him to choose eighter him or the hotel (Which include the cast.), him being the selfish guy we know him for would likely choose the option that benefits him. But I think that act could accidently spiral into something that indirectly counteracts his defying trait, which inevitably gets him redeemed. IDK if I'm crazy or not, I'm just a guy with too much free time and likes a musical every now and then LOL. Anyway, have a good day!
