In scene 2 it shows how Macbeth feels guilty for killing Duncan, “will all great Neptunes ocean wash this blood clean from my hand?”, as Macbeth said. When he says this it makes me think really hard because he’s saying a rhitorical question that he knows the answer too.He has realised that what he done was wrong so he askes the god of the sea “Neptune” to wash his hands free of what he has done because he regrets killing Duncan and now he has a guilty consouince.
