Albus Dumbledore

Albus Dumbledore Hagrid seems innate confidence in any situation, starting from when Hagrid attended Hogwarts. Dumbledore believes that Hagrid did not open the secret chamber, and asks the former Rector Armando Dippet train as groundskeeper Hagrid, so that he could stay. Since then, Dumbledore has many examples of his faith in Hagrid. For instance, Hagrid has a job is to protect Harry because he has brought to life together with the Dursleys, and asked to return to the Philosopher's Stone Gringotts. Dumbledore sent Hagrid other important tasks, such as trying to convince the giants to join the side of Phoenix.
