In 'Harry Blames Dumbledore' fanfiction, a frequent theme is the idea of manipulation. Harry may come to believe that Dumbledore was manipulating him throughout his years at Hogwarts. This could include things like using Harry as a pawn in the fight against Voldemort without fully disclosing the risks. Another theme can be the exploration of Harry's emotional growth. His blaming of Dumbledore can be a catalyst for him to become more independent and less reliant on the guidance of others, forcing him to figure things out on his own.
Another reason could be his sense of responsibility for the whole wizarding world. Since he's the 'Chosen One', he might blame himself for every setback in the fight against Voldemort. He may think that any harm that comes to the wizarding community is due to his own inadequacies in leading the fight or in not being powerful enough quickly enough.
