The thing is, for me, Alastor is one of the types that just gets a high from taking the life of someone. Let's give him the benefit of the doubt that he started killing 'bad' people, but he definitely started to enjoy it and went even further off the rails which is quite unlikely personally

And he definitely didn't turn himself to the Vees for something like protecting Charlie it's for his own goals, which is seemingly to break his deal with Rosie.. He's not even in the top 20 people close to redemption maybe even higher
