He creates a monster by experiment. The monster was kind, and ready to help others. But he is not accepted by the society just because of his ugly appearance. People around him refuse his kind offer and turn him down. Some even drive him away. He is eager to get love and happiness, but unfortunately what he gets is merciless chasing. He asks Frankenstein, the scientist to create a female monster like himself so he can have a company, but again he was refused. In all his life he lives a miserable life. At last he cannot bear all these. He chooses to avenge humans. At last he dies together with his creator, Frankenstein.
