Answer:
Step-by-step explanation:
To ensure that Macbeth becomes king, Lady Macbeth creates a plan to kill the current king in his sleep. In further detail her plan includes to first get the guards drunk so she will be able to successfully sneak into his room, Macbeth will kill Duncan (the current king), and then blame the crime on the guards who will have no record of what happened. However she believes that there are loopholes behind her plan. The plan is set and has the probability of working out, however she fears Macbeth. She believes Macbeth lacks the cruelty to kill Duncan on the spot and in his room.
