Firstly, having very high Ambition jolts Macbeth to go beyond being the Thane of Cawdor. This is proven when Macbeth says, “If good, why do I yield to that suggestion whose horrid image doth unfix my hair and make my seated heart knock at my ribs” (1.3.138-140).

When saying this, Macbeth vows to act upon instinct from then onwards. This is one of the ways Macbeth is
