The play Macbeth is about the character Macbeth, but not just because it is his name, he is an interesting person. Macbeth is the thane of Glamis and Scottish general who is told that he will be king by three witches. He kills King Duncan to bring the prophecy to fruition. He deals with a lot of self conflict because he is not comfortable with his decision to kill King Duncan, and later on Banquo.
