The monster is created by Victor Frankenstein while at the University of Ingolstadt."Formed into a hideous and gigantic creature," the monster faces rejection and fear from his creator and society. The monster is the worst kind of scientific experiment gone awry. He does acquire humane characteristics, even compassion for his "adopted" family, the De Lacey's, but he still murders for revenge. The creature also begins to learn about himself and gains general knowledge through the books he reads and the conversations he hears from the De Lacey's.
The monster represents the conscience created by Victor, the ego of Victor's personality — the psyche which experiences the external world, or reality, through the senses, that organizes the thought processes rationally, and that governs action. It mediates between the impulses of the id, the demands of the environment, and the standards of the superego.
