Answer:
Students should discuss the statement considering the similarities and differences in the murders and explaining the changes in Macbeth revealed by the plot to murder Banquo. For example, students may point out as similarities that Macbeth is responsible for both murders, commits them for power, and pretends to honor both men even as they are being executed. As differences, students could say that Duncan was a mighty king, while Banquo is Macbeth’s peer and friend. Macbeth kills Duncan with his own hand but has henchmen murder Banquo. Students may suggest that Macbeth is more calm and organized in his plan to murder Banquo. He almost carefully plans the crime so that it won’t reflect on him without the fears that plagued him at the death of Duncan. He is more used to such evil.
