Is Macbeth mad?

Is Macbeth mad?  -Soliloquy

Macbeth seems to be going insane in scene two act one, because he is constantly talking to himself. “Art thou not, fatal vision, sensible /To feeling as to sight? Or art thou but/ A dagger of the mind, a false creation,” (2.1.37-39) Macbeth sees a dagger but he isn’t able to touch and he continues to tell himself that it is not real and that his mind is making it up, this makes him out to be insane, because he is continually talking to himself about why the dagger is there and why he can’t touch it. “As this which now I draw./ Thou marshall’st me the way that I was going, /and such an instrument I was to use.” (2.1.42-44) Macbeth is saying how the dagger is there because that is the exact same weapon he was going to use to kill the king.  “And on thy blade and dudgeon gouts of blood,/ Which was not so before. There’s no such thing./ It is the bloody business which informs” (2.1.47-49) Macbeth is starting to believe that the dagger is to show him that he is doing the right thing and how it is right that he is going to kill the king. Macbeth is going insane because of the thought of killing an innocent person who has been chosen by the divine right to rule.
