Did Macbeth Kill Duncan or Himself?

Did Macbeth Kill Duncan or Himself?

In the play “Macbeth”, Macbeth destroys himself as a human being by killing Duncan because he was eventually consumed by the same thirst for power that drove him to his evil ways. This thirst for power caused him to become paranoid and to begin losing his sanity. Consequently, he became more murderous and by listening to the witches’ prophecies, he became overconfident and completely ignored his surroundings. This lead to his demise.

Macbeth ultimately destroys himself through his paranoia, which causes him to lose his sanity. Macbeth was a very nervous king, he wanted all the power that he could achieve but was always in constant fear of his life. Therefore, his fear played tricks on his mind that made him believe that he would also be killed by someone seeking the same power he sought. The end-result was that Macbeth slowly lost his sanity and was very apparent to the people of his court.
