Macbeths mental state

1) I think he is mad because he doesn’t even know what he’s seeing like when he says ” is this a dagger which I see before me.”

2)In this quote he says “Will all great Neptune’s ocean wash this blood.” Which means he does t think he can wash the guilt away for killing Duncan.

3) in act 1 scene 7 Macbeth says in his soliloquy “who against his murderer shut the door, not bear the knife myself.” I think this means he is confused he doesn’t know what to do whether to kill Duncan or not.

4) I also think he is mad because only him and Banquo can see the witches. An evidence of him seeing the witches is in act 1 scene 3 he says “into the air, and what seemed corporal, melted, as breath into the wind. Would they had stayed.” I know this is talking about the witches because the witches vanish then he says that.

5)In act 1 scene 7 in this quote he admits he is going to kill Duncan “when we have marked with blood.” I think this makes him mad for power because he knows he will become king but now he’s going to go and kill him.
