Macbeth is a play about death, deception and corruption. At the center of it all are Macbeth and his wife, Lady Macbeth. As the play progresses, their relationship changes dramatically due to how each of them deals with their emotions after the murder of King Duncan. At the beginning of the play, Lady Macbeth is a strong and domineering person. She seems capable of forcing Macbeth to do things he would not do alone. She seems ready to trample on anyone to get what she wants. She looks ready to kill. She would have no problem dancing on the backs of the bruised for the same reason that today's uptight rich don't care about starving children in Africa - she has never seen or experienced that. Reading Macbeth's letter which spoke of the witches' prophecy, she says: “Yet I fear thy nature; she is too full of the milk of human kindness to take the nearest path. » She wanted to take the quick and dirty route to royalty (murder), but didn't think Macbeth was up to it. She's never killed anyone (that we know of), so she doesn't understand why this would be so difficult. Macbeth is a seasoned soldier who is no stranger to danger. He killed many men, women and children in his time. We are made aware of this at the play's opening when a sergeant recounts how Macbeth stalked Macdonwald and "undid him from the seams of the nave to his leggings and fixed his head on our battlements." But Macbeth knew the difference between good and evil. Macdonwald was a traitor and fully deserved to be cut in two. Killing Duncan was another story. Murdering a good king/friend in order to gain wealth and power is not very PC and is downright immoral. When Lady Macbeth brought up the king's murder, he hesitated to talk about such a thing, then blew it off and said, "We'll talk about it again." Of course, being the whipped mama's boy that he is, he was convinced of her evil conspiracy plan. In the end, Lady Macbeth could not kill Duncan. She said: "If he hadn't looked like my father in his sleep, I wouldn't have done it." Of course, this is a load of bullshit; in reality, she was simply too shy to do the job.
