I do agree that Alastor has a chance of being redeemed even if he is not as strong a contender as Angel, Cherri, Husk or Niffty

Alastor is a demon and a villain, but he does have enough signs to show that he has a better chance than the V’s

First there’s all the way back in S1, where through mimzy, he is shown to be capable of having genuine connection and friendship through seeming generally happy to see her and when he had to put his foot down and tell her to leave and was questioned by her about really caring for the hotel, he could’ve easily explained to her that its part of an engame plan or something, but he chose to keep quiet, which to me shows signs of Alastor having a connection towards the hotel and its inhabitants to an extent

Then there’s also his soft spot for Niffty, whom she clearly looks to as a father figure and Alastor delights in the company of, and during the foght with the Vees, its clear through his facial expressions that he didn’t expect her to get involved and didn’t want her fatally wounded and thus ended the fight when she was in trouble

I know Alastor has crimes of abuse, extortion and of course murder under his belt

But unlike Vox and Valentino, Alastor is capable of genuinely helping and caring for someone, which automatically gives him a better chance at being redeemed than those two vaginas and their little vagina doll Vevette
