According to author J. K. Rowling, Harry Potter is strongly guided by his own conscience, and has a keen feeling of what is right and what is wrong. Having "very limited access to truly caring adults", Rowling said, Harry "is forced to make his own decisions from early age on." He "does make mistakes", she conceded, but in the end, he does what his conscience tells him to do. According to Rowling, one of Harry's pivotal scenes came in the fourth book when he protects his dead schoolmate Cedric Diggory's body from arch villain Lord Voldemort, because it shows he is brave and unselfish.
