First I look forward to Alice maybe getting a second chance at a better life. I also hope Arnold does help his summons live life outside of just servitude to him and constant combat. Second, I think he should have killed Allen. Letting him live forces Nathaniel to either kill him or exile him but regardless of that choice the pain that would cause him is much more than if Arnold took care of it himself. Yes, Nathaniel might him for a while but Arnold should just carry that hatred because its better to hate Arnold than to grieve for a POS son. Which ultimately Nathaniel failed, since its a parent's job to raise his kids into somewhat decent human beings. Arnold does owe Nathaniel at least that much.
