When a leader believes himself to be infinitely secure, as Macbeth felt in the witches' prophesies of him being king, a lot can go wrong.  Macbeth,  a brave warrior who gave into his innate ambition, showed that a certain level of ambition is beneficial if directed towards the public good of a society, as it motivates one to connect with their subjects and make changes accordingly; however, excessive ambition, spurred on by false security and lack of checks from moral authority, tragically destroys and detriments societies in critical ways as leaders depart from the connection with their subjects and focus on personal glory and lustful vengeance, as did Macbeth.
