Which best explains Macbeths growing sense of guilt

Macbeth’s guilt is seen when he cannot enjoy the success he has gain with taking the throne and killing the king. This is one sign of Macbeth’s guilt over his actions. Even as he begins killing those he sees as a threat to his rule, it brings no peace to him. His guilt can best be seen when Banquo’s ghost appears to him at a banquet. Upon seeing Banquo’s spirit, he nearly admits his crime had his wife not calmed him down.
