Macbeth's Morality

Macbeth's moral conditions worsened since the three witches prophesized Macbeth and Banquo.
Before the prophecy of the witches, Macbeth have done nothing to feel guilty. The prophecy of the witches is the initiation of Macbeth's morality decreasing. After hearing the prophecy, Macbeth thought of the probability of killing the King Duncan. Macbeth's morality fell dramatically when he decided to kill Duncan for sure and also when he killed Duncan. The death of Duncan made Macbeth uncertain of the security of the position of being king. He ordered two murderers to kill Fleance and Banquo which made him more guilty of his actions since Banquo was his best friend. As plot passed, his morality fell more and more as well as him feeling more guilty.
