"All right, class. We've almost finished our study for Macbeth. We've watched Macbeth change from a noble, trusted, dedicated soldier...to a wretched, depraved, corrupt murderer...It's a fascinating study of the degeneration of the human spirit."
Literary Device: Allusion (reference to a well-known person, event, place, literary work, or work of art)
Analysis: This allusion is effective because Macbeth is similar to Andy. Like Macbeth, Andy also has undergone a "...degeneration of the human spirit." He is trapped by his guilt and has declined emotionally. His grades are slipping, he is acting out in class and doing poorly academically.
