I understand that you want some of the hero's misfortunes to be attributable to things he himself did, in some sad or terrible irony, because otherwise it's like the universe just hates him and he's always a victim. So Cedric dies because Harry tried to be generous and fair; Sirius dies because Harry didn't look at what he gave him, and because Harry was too impulsive and caring; the Death Eaters figure out which of the seven Harrys is the real one because only Harry uses Expelliarmus instead of Stupefy; and the trio gets caught because Harry is known to be one of the few people who refuses to not use Voldemort's name. Sometimes the things that cause the misfortunes are things he shouldn't have done; sometimes it's someone actually using good things he does against him. So I understand that this is how you want to structure the hero's tribulations, because he shows that he has agency in the world, and when he acts, the world pushes back--things happen to Harry because he is Harry and because of the actions he chooses to take, not because it's just random or coincidental shit that could befall anyone.

But JFC, could we lay off the kid after a while? I don't know if they have wizard therapy, but someone needs to look into getting him some.
