 Studying with Beth, let's discuss how his characters dramatically change and he's become totally corrupted by ambition by Act 4 Scene 1 when he meets the witches. In Act 4 Scene 1, McBeth says how now are you secret black Midnight had? Now this exclamatory sentence is a complete contrast to how he was when he first met them in Act 1 Scene 3 when he was really scared. Now he's being really rude, quite commanding. Shakespeare uses the rule of three when McBeth is describing the witches as secret black at midnight. McBeth feels he controls the witches he says I can enjoy you by that witch you prefer. Now the Iron bit pentameter and what he says here shows he thinks he can actually control his destiny. He understands the witches have the power to untie the winds and let them fight. When he says let them fight he's using personification here to show how the witches have the power to do really unnatural things to the weather. He shows his awareness the witches cause chaos. Though bladed corn be lodged and trees blown down, their castles topple on the water's heads. In other words the witches can do anything that causes chaos. The repetition of the words though show that McBeth is really silly. He understands the witches can cause lots of chaos but it doesn't think that they will also cause chaos to him.
