Macbeth pretending to be a loyal servant of King Duncan but eventually murders him in order to steal the throne.
Explanation:
The recurring motif in <em>Macbeth </em>“Fair is foul, and foul is fair” means that looks can be deceptive as someone who has a good appearance or seems "fair" is actually bad or evil which is the opposite of being fair.
The words “Fair is foul, and foul is fair” was actually said by the witches when they were making incantations at the beginning of the play.
