The theme of how Ambition corrupts Macbeth’s mind is illustrated through Macbeth’s soliloquy in Act 3, Scene 1, he is acknowledging Banquo is a threat and how Macbeth may have taken the throne, but only to have it passed on to Banquo’s family not his own. Macbeth continues to complains how he has ruined his own peace for their benefit then states he want’s to challenge the fate he’s been given and fight his way out of it.
Macbeth’s mind is shown to be corrupted through the technique of foreshadowing. Macbeth is venting about Banquo’s prophecy and how he cannot pass the throne onto his family. Macbeth is deciding to take action and foreshadows what’s going to happen to Banquo in the future. “Rather than so, come fate into the list, And champion me to th’utterance” This quote conveys the idea that Macbeth’s mental state is deteriorating as his ambition to maintain his throne and keep throne within his bloodline, is starting to take over his mind.
Macbeth uses royal imagery to connect Banquo to someone is royal or royal in nature. Macbeth admits that Banquo would be a better king them himself and how he feels threatened by this. “Our fears in Banquo stick deep, and in his royalty of nature reigns that which would be feared”. Connecting Banquo to royalty conveys the idea that Macbeth is worried about his position as king and how long his reign will last. It also hints that this threat is driving Macbeth’s ambition to be king and maintain his throne.
Macbeth’s Ambition is powerful and he is willing to risk anything to be king, This is illustrated through foreshadowing and royal imagery.
