Shakespeare presents Banquo as skeptical towards the supernatural, shown in "Instruments of darkness tell us truths; win us with honest trifles, to betray's". The metaphor of "instruments of darkness" conveys that Banquo is of a higher moral standard than Macbeth, he understands that the witches are trying to lead them away from their christian morals and values. It's also foreshadowing the events in the rest of the play, the noun "darkness" suggests that Macbeth will be led down a dark path, referencing that he will go on to commit regicide and consort with the supernatural. This is Banquo's word of warning to Macbeth as he knows his character, he is highly ambitious, and Banquo fears that he will commit great sins in order to achieve what he wants. This shows us that Banquo is a good and moral man, he is told by the witches that his sons will be kings but he does not celebrate or dwell on it, he instead reminds himself and Macbeth that the witches are sent by the devil to draw them away from God. Shakespeare presents Macbeth is conflicted by the witches prophecy, shown in "If ill, why hath it given me earnest of success". This rhetorical question shows Macbeth is not as morally strong as Banquo and is easily led by the temptation of power. The fact it is said in an aside also shows his confliction further as it's his internal monologue speaking, giving us a better understanding of what Macbeth's actual thoughts are. He goes on to contradict himself in "whose horrid image doth unfix my hair" this metaphor shows that Macbeth is already thinking of killing Duncan in order to fulfill the prophecy and become king. the adjective "horrid" shows that Macbeth is still aware of his morals and standards. Shakespeare is showing the supernatural causes unnatural thoughts which links to the theories in king James book, daemonology. Macbeth is further presented as disturbed by the supernatural, shown in his reaction to Banquo's apparition, when he says "let the earth hide thee!". This exclamation shows Macbeth has lost control of his situation, he did not listen to Banquo's warnings that dealing with the witches would lead to dire consequences. Macbeth believed he was in control when in reality the witches have had the upper hand the entire time and he now has to face the guilt and punishments that come along with his sins. Macbeth is further presented as disturbed when he says "never shake thy gory locks at me!", Banquo is shaking his head at Macbeth shaming him for his murderous actions. The imperative of "never" shows Macbeth is trying desperately to maintain his power over the supernatural, trying it make it his servant rather than he be it's servant. Shakespeare is trying to get across that the supernatural is more powerful than anyone person, including the king. This backs up king James's theories and beliefs in witches, which is why he has included it, in order to please the king.
