Angel Within

The funny thing is that Dumbledore knew Lockhart was a fraud before hiring him. According to J.K. Rowling’s official backstory, Dumbledore knew two wizards whose achievements Lockhart had stolen and believed that placing him in a normal school environment would expose him as a charlatan. When Professor McGonagall questioned what students could possibly learn from such a vain, incompetent man, Dumbledore argued that even a terrible teacher could demonstrate what not to do. He also exploited Lockhart’s obsession with fame by dangling the opportunity to teach Harry Potter in front of him. There was another problem: the Defence Against the Dark Arts post had become notoriously difficult to fill because of the curse associated with it. So Dumbledore wasn’t fooled by Lockhart’s books or celebrity status; he deliberately hired him, expecting his lies to unravel. But Dumbledore’s reasoning doesn’t completely excuse the decision. In Chamber of Secrets, Lockhart releases Cornish pixies into a classroom, fails to demonstrate basic defensive magic, and attempts to flee when Ginny is taken into the Chamber. His incompetence becomes especially dangerous when he tries to erase Harry and Ron’s memories with Ron’s damaged wand. The film adaptation preserves these key failures, making Lockhart entertaining to watch but also highlighting how little the students learn about defending themselves. Rowling’s explanation gives Dumbledore a deliberate motive, but it also raises a fair criticism: exposing a fraud is not the same as protecting children’s education. Hogwarts was facing a genuine threat that year, and practical Defence Against the Dark Arts lessons mattered. Dumbledore wanted Lockhart exposed, but the students paid the price for turning a classroom into a stage for that lesson.
