Loyalty

Loyalty is a theme central to the novel and the main characters. Those characters that are loyal and faithful are the strongest characters. Harry remains loyal to his friends and to the power of good magic, even when it seems as if this is the wrong thing to do. Tom Riddle tries to influence Harry and convince him of Hagrid's guilty part in opening the Chamber of Secrets but Harry remains loyal to Hagrid. Harry's loyalty to Dumbledore also helps him to defeat Voldemort. Fawkes, Dumbledore's magical phoenix, comes to help Harry when he most needs it, and this is a direct result of Harry's loyalty to Dumbledore. Harry's loyalty towards his friends is also what motivates him to enter the Chamber of Secrets, to defeat the Basilisk, and to save his friends.

Loyalty can also be seen in the dark characters, giving them strength in their beliefs...
