do I yield to that suggestionWhose horrid image doth unfix my hairAnd make my seated heart knock at my ribs,Against the use of nature?’Macbeth is showing here that deep inside him, there are forces that want him to take action to become King, even if this action is murder. In a way, this scares him, as it would you or me if in his position. It is already starting to show that he is brave in battle, but fragile in mind. Macbeth’s conscience works well for him at first by helping him reject the idea of murder, as Macbeth tells himself:'If I chance will have me King, why, chance may crown me,Without my stir.'This means that if the witches’ prophecies are true, then he will become King whatever the circumstances, so he wouldn't need to commit any crimes, for example murder. By the end of scene four, Macbeth realises that he may have to take some action to become King, whether it be murder or not. His soliloquy indicates that he wants no one to see what he feels, and what he wants to do. He admits to himself that he has black and deep desires locked up inside him, which he does not want anyone good to see, as he says:“The Prince of Cumberland! That is a stepOn which I must fall down, or else o’er leap,For in my way it lies. Stars hide your fires!Let not light see my black and deep desires;” From one of Macbeth and his wife’s first conversations, he proves his reluctance to give his wife a final decision on the matter. As he says:“We will speak further.”He seems to have developed an uncertainty about the situation, and fails to stand up to his wife for the first time and say, “I will not murder the King”. He hasn’t completely dismissed the subject, but so far it is in his best interests to let his wife know that he is not all for the idea of murder. This would help her understand Macbeth’s side of the story, so she would not be so much against him....
