The conversation between human and AI assistant.
Why were the Dursleys allowed to treat Harry the way they did? Why did the neighbours or teachers not report them to the appropriate authorities?
And what about Dumbledore? Do you think he could have done more to help Harry?
It's certainly possible that Dumbledore could have done more to help Harry. However, it's also possible that he believed that Harry needed to endure some hardship in order to develop into the person he needed to be.
