The Banquos death, because he didn’t have to

The role of a tragic hero is common in most plays, books, movies, etc. Most of Shakespeare’s plays involve a tragic hero. In the play of The Tragedy of Macbeth written by William Shakespeare, Macbeth is the tragic hero. It is important to understand what makes up the characteristics of a tragic hero. Typically, a tragic hero is a figure of high stature, often of noble background. This person is mainly good, but suffers a self-inflicted falling out due to flaws in his or her personality. The tragic hero has a tremendous downfall, brought about by their weakness. In Shakespeare’s Macbeth, the main character of the play is seen as a tragic hero. 
Macbeth is introduced in the the play as being well-liked and respected by the captain and the people. Which is a common start in tragic heroes. “O valiant cousin! Worthy gentleman!” (1.2. 24) After the witches told Macbeth about his bright future of nobility, his honorable nature seemed to fade, and was soon replaced by a “by any means necessary” attitude. The witches affect his perception by telling him what is going to happen in the future and they make him paranoid. His lust for power, along with persuasive words from Lady Macbeth, led to him murdering King Duncan in his sleep. 
Macbeth is hesitant when he is thinking about killing Duncan. “Words to the heat of deeds too cold breath gives.” (2.1. 63) After Duncan’s murder, Macbeth becomes overwhelmed with guilt and anxiety. He hears a voice cry out that he will never be able to sleep peacefully again because he murdered Duncan when he was asleep and helpless. Macbeth is filled with so much guilt that he thinks there is so much blood on his hands that, if he plunged them into the ocean, his blood would turn the whole ocean red. His guilt soon fades ways, when he has no hesitation to order his next murders.
A while after Duncans death, Macbeth doesn’t worry about his guilt, but now he is more focused on maintaining his power. One person who is in the way of his power is his former best friend Banquo. Macbeth orders his murderers to kill Banquo and Banquos son Fleance. Macbeth is afraid of Banquo, because of the second part of the witches’ initial prophecy. The prophecy stated that Macbeth would rule Scotland, but it would be Banquo’s heirs, not Macbeth, who would eventually inherit the throne. During the celebration feast, after Banquo has died and his son escaped and fled. Macbeth feels less guilty about Banquos death, because he didn’t have to do the killing himself. But during the feast Macbeth sees the ghost of Banquo. “This is the very painting of your fear.” (3. 4. 64) Macbeth is struck with fear when he sees Banquo’s ghost. This is a turning point in the play, because we see Macbeth express his internal guilt for the first time. The ghost then reveals the fear and paranoia that Macbeth’s deeds have caused. He worries that macduff, who didn’t attend the feast may be conspiring against him, and Macbeth decides he must seek advice from the witches.
Macbeth is sinking deeper into his insanity. He is consumed with doing whatever it takes to keep the throne. After visiting the witches and seeing the apparitions, Macbeth believes that Macduff is the only one who stands in his way of maintaining the throne. With Macduff in the way, this frightens Macbeth so he wants to get rid of Macduff. Since Macduff has fled to England, leaving his family alone in his castle. Macbeth kills Macduffs family, the reason for the murderer of Macduffs family is to clear the bloodline. “The castle of Macduff I will surprise,/ Seize upon Fife, give to th’ edge o’ th’ sword/His wife, his babes, and all unfortunate souls/That trace him in his line.” (4. 1. 157-160) When Macduff finds out the news of his family he is devastated. He now wants Macbeth to pay for his actions. 
In Act 5 now we see Lady Macbeths guilt getting to her. So much that she is sleepwalking and later commits suicide. Now it’s all on Macbeth, with an army coming to take Macbeth down, he is fearless because of the prophecies told by the witches. He believes is unstoppable and his cockiness leads to his downfall. The prophecies made Macbeth do little to protect his castle. He was surprised when he was told that the forest was attacking his castle, which was actually Macduff’s army. His true downfall came during his battle with Macduff, where Macduff revealed he was not born of woman, rather he was ripped form his mother’s womb. In this moment Macbeth was enlightened about his vulnerability. Macduff goes on to behead Macbeth. With his death, Macbeth solidifies himself as a tragic hero. The audience learns the dangers of ambition, and good is reestablished. 
Macbeth’s tragic flaw is his ambition and it consequentially leads to his downfall and ultimate demise. In the play, Macbeth possesses many strengths such as honor, respect, and he was viewed as being courageous. Macbeth’s strengths turn into his weaknesses and his ambition drives him to the edge and sets himself up for his tragic death.
