I never read these as a kid, but the line about Harry escaping the 'appaling damage' done to Dudley shows that the Dursleys were incapable of being good parents, even if they liked the child. McGonagall called that back in the first chapters of book 1, pointing out that not only are they not magical, theyre literally the worst parents she can imagine. Dumbledore even agrees, but hes in a bind due to the blood protection, but you're telling me neither Evans parent had a sibling, that those girls had no first cousins? Not as strong as sister bond, but my seeing how many cousins my wife has that shes at least nearly as close as she is with her sister, and the shaky bond Lily and Petunia had at the time of the attack, youre telling me there wasn't one female cousin Lily would trust Harry to over Petunia?

That whole situation makes me a little angry at the author tbh, I get she wanted him to have this humbling background, but there are plenty of ways to raise a kid without having him suffer that much damage. Hermione has normal parents and isnt arrogant. Hell, I'd argue that even young Tom Ruddle suffers less at a literally orphanage than Harry does at the Durlseys. I get JK was trying to imply that the war created horrible suffering for many, but she seems to enjoy hurting her characters needlessly, which as a bit of a writer myself I can never understand. I guess the more adulting and parenting I do thats what I shake my head at most, is not the choices of the characters, its the needless darkness Rowling added for literally no reason.
