Macbeth is an Anti-hero

I believe that Macbeth is an anti-hero because he lives by his own flawed morality. He disregards common decency when he kills his good friend Banquo, innocent women and children (lady Macduff), and his own king Duncan. I believe that he is an anti-hero because he knows what he is doing that is wrong, for example the beginning of the play when he ponders whether or not to kill King Duncan. However as he continues to kill these people his mind starts to whither away and he becomes crazy. The stress of the dreadful deeds took this toll on him and he continues to kill. He disregards what his society believed to be courteous and was not a decent king, which he saw a good example of in King Duncan. When Macbeth listens to the prophecy he makes a decision to be indecent and kill all the people that he did, therefore he is an anti-hero.
