This one of the main ideas that runs through this novel as you learn more about each character. Does Victor have a moral obligation to make the creature happy?
Victor does not look at his creation as that of a parent. He sees himself as a scientist and the life he created is simply an experiment. Once the experiment has been completed and he sees the result of his labor, he is disgusted with the appearance of the monster as "his yellow skin scarcely covered the work of muscles and arteries beneath". Victor was more concerned with the idea of completing the experiment, not creating life. Therefore, upon seeing this creature, he is disgusted and runs away. This is his reaction to the life he has created. The creature tracks Victor down and upon waking, Victor sees the creature standing beside his bed. "His jaws opened, and he muttered some inarticulate sounds, while a grin wrinkled his cheeks. He might have spoken, but I did not hear . . . I escaped and rushed downstairs."
Victor runs from his creation and from his memory of creating it. When the creature and Victor finally speak to each other, the creature tries to make Victor understand how he abandoned his responsibilities toward his creation. The creature tells him, "remember that I am thy creature; I ought to be thy Adam, but i am rather the fallen angel, whom thou drivest from joy for no misdeed."
The creature certainly believes that Victor has been a bad "parent". Victor never felt any responsibility toward the creature because the creature was simply an experiment. Unfortunately, by the time the creature confronts Victor about his responsibility, Victor feels hatred for the creature due to what the creature has done to his family.
