Please revise hte short paragraph plz its urgent?

During the medieval era, people believed in the Great Chain of Being, the idea that rulers are appointed by God, and through their authority the will of God was carried out. To kill a ruler is to attack God. Macbeth's treachery is a metaphor for man's fall from grace. Attempting in darkness to conceal his actions is similar to our primordial Adam's covering his nakedness with a fig leaf. While Macbeth plans to commit unforgivable crime in his castle, King Duncan chooses to visit his castle because he thinks he is under God's protection and Macbeth is loyal to Duncan. However, after murdering King Duncan, Macbeth disturbs the Great Chain of Being, which causes more tragedy. He kills Banquo to maintain his kingship, witnesses Banquo's ghost, and is eventually murdered. In this way, King Duncan proves his absolute power even after death.
