” (1.3.50-54)As soon as Macbeth learned of his future, he began to scheme on just exactly how he would fulfill these prophecies. That is when he decided that he would have to murder Duncan to fulfill the last prophecy.
But that is when he had a change or heart. The only problem with Macbeth deciding not to murder Duncan, is that all of a sudden Lady Macbeth became the power greedy one. This is when Lady Macbeth’s scheming began. Although Macbeth had changed his mind and basically refused to murder Duncan, Lady Macbeth was able to eventually convince him to carry through with the plan.
Even though Macbeth was the one who executed the plan, Lady Macbeth was the mastermind behind the scheme. Her greed for power was the one major factor that possessed her to convince Macbeth of the plan and carry through with it. Macbeth murdered Duncan at Iverness, and became hysterical after doing so. As a result of Malcolm and Donalbain’s suspicions resulting in their departure to England and Ireland Macbeth became king: this was the ultimate power that he and Lady Macbeth had as their goal (well, actually it was more of Lady Macbeth’s goal), and now he eventually had received it.
Nothing was going to take away this ultimate power from Macbeth, and he would do anything to keep it. Macbeth’s ruthlessness results in him ordering three murderers to murder his best friend, Banquo. The power of being king has taken over Macbeth’s life, and he is a victim of his own greed for power. He is a tyrant.
Not only does Macbeth murder Banquo (not directly, of course), he also murders (actually he has people murder) Macbuffs family. Macbeth does not murder Macduff, but he does murder his wife, children, and servants. Macbeth can not stoop any lower than the level that he is currently at. Now, it is Malcolm’s turn to want the power of kingship.
The reason that Malcolm desires to become king, is because he knows that Macbeth is a murderer and a tyrant. Malcolm feels confident that he will be a fair and just king. At the end of the play when Malcolm comes into kingship, he is a gentle and kind ruler already.
