The monster is a very intricate character: He's innocent but murders, he's loving but also filled with hatred, he loves humans but is tormented by them. The monster tells Victor that he was born a loving person, and was forced to kill William, Elizabeth, and Clerval. (He tells Walton that he didn't actually enjoy killing them, and that he hated himself more every time he did it) Eventually, once Victor dies, the monster says that he's in complete anguish, and vows to travel into the North Pole and set himself on fire.
