Not only does it cut deep into Dumbledore’s image as a paragon of the Light, it also casts tremendous doubt on his judgements and decisions, going back as far as to when he was a mere teacher at Hogwarts rather than headmaster. Harry isn’t one to hold out hope for miracles, but perhaps this will motivate the Wizengamot to re-evaluate at least the Death Eater trials. Hopefully, with liberal use of veritaserum.
