Final answer:
The planning of Banquo's murder is different from that of Duncan's in terms of motive, premeditation, and the execution of the plan.
Step-by-step explanation:
The planning of Banquo's murder is quite different from that of Duncan's. Firstly, the motive for Banquo's murder is different. While Macbeth murdered Duncan to fulfill his ambition and gain power, Banquo's murder is motivated by Macbeth's fear and insecurity about the prophecy that Banquo's descendants will become kings.
Secondly, Banquo's murder is not premeditated, unlike Duncan's murder. Macbeth hires murderers to kill Banquo, whereas the murder of Duncan was meticulously planned by Macbeth and Lady Macbeth, who drugged the guards and stabbed Duncan in his sleep.
Lastly, the same plan is not used for both murders. The murder of Duncan involves framing the guards, creating an alibi, and manipulating suspicion, while the murder of Banquo is more direct and involves hiring assassins. Therefore, the planning of Banquo's murder is quite different from that of Duncan's.
