Answer: Both plays reflect on the universal theme of a tragic hero.
This is a characteristic that both plays have in common. In both plays, Macbeth is a tragic hero because he is a person who begins as admirable and moral, but is lead astray by a character flaw. In this case, Macbeth's character flaw is his greediness and ambition. He desires power, and he is willing to do anything in order to have it. This tragic flaw leads him to a sad destiny.
