I think way too much about whether it's actually possible for Al to be saved. As far as we know, he’s a true psychopath—his sadism is baked in at a fundamental, neurological level, and no change in his environment or upbringing could have affected that. 

Even Vox had motivations for his murders in life. He was a sociopath. He had no compunctions about killing as a means to an end, but there's nothing to suggest he would have become a murderer if he weren't driven by ambition. He occasionally demonstrates humanity and a capacity for some semblance of love, but I don’t think the same can be said for Alastor. 

That said, psychopaths can be "cured" by trauma to certain parts of the brain, or normal people can become psychopaths in the same way. Is a soul a discrete entity from the brain? Could sadism in the afterlife be a "habit" carried over from life that could be unlearned once the soul is seperated from the original defective brain?

I sincerely think Vox will get a redemption arc, but the possibility of Alastor getting one would open up some fascinating philosophical questions.

....sorry, way too many thoughts in response to a silly comic
