Dumbledore and the Dark Knight

Harry still believes that Dumbledore can do anything. He's the only one Voldemort ever feared. So he trusts Dumbledore blindly into like keeping him in this cage and keep him in the dark. If he didn't have to, I think that's just what breaks his trust. And that's what makes it so difficult when he when serious is also not on the side was also very powerful and magical. The last hope he has is getting to Hagrid. Who's this who's on the same level as him? But then he's not there.
