Victor says, "A flash of lightning illuminated the object, and discovered its shape plainly to me, its gigantic structure, and the deformity of its aspect, more hideous than belongs to humanity, instantly informed that it was the wretch, the filthy daemon whom I had given life." Victor knows the truth now; his creation has murdered William. When he gets back to his house he learns that little Justine has been accused of the murder. She will die for it unless he speaks up. He acts as if he is God and makes the decision to be quiet about what he knows.2 Again he becomes self-centered in the situation and thinks he has the right to be quiet, not realizing that humanity demanded that he admit his faults, if only for innocent Justine's sake. Victor, in playing the role of God, brings more horrible results; it causes an innocent girl to be put to death. .
Now we are toward the end of the story, and Victor still plays the role of God, which brings him madness of the mind. Victor says, "I was hurried away by fury; revenge alone endowed me with strength and composure And now my wonderings began, which are to cease but with life. How I have lived I hardly know But revenge kept me alive; I dared now die, and leave my adversary in being." Victor thinks of how his friends and family are dead and how he lives, and their murderer lives. He thinks that he alone can destroy the demon. He becomes self-centered and acts like he is God in making the decision that he alone will destroy the monster that plagued so many people. It comes to the point where it drives him to madness, and he becomes obsessed with the destruction of the monster.3 Playing the role of God can have horrible results on the physical as well as the mental aspects of a human. .
As one can tell, playing the role of God can produce horrible results, which one can learn from Mary Shelley's Frankenstein. Playing God is a continuous state of mind for Victor in the novel.
