When Macbeth needed to maintain the throne he targeted his best friend Banqou because he threatened its security when the witches’ predicted Banqou’s children becoming the hier to the throne. Macbeth doesn’t hesitate when he plots how to commit his second murder. Macbeth arranges murderers to kill Banqou and his son. Macbeth’s guilt takes the form of a hallucination of the ghoust of Banqou after it is confirmed that he had been killed. At this point Macbeth’s guilt is becoming less intense and he no longer hesitates when protecting the throne which shows how Macbeth’s nature is becoming more evil.
Macbeth orders the murderers to kill Macduff’s wife and child out of anger against Macduff. The witches’ again use their predictions to pave the path of Macbeth’s demise by sharing with him that the only competition Macbeth has left is Macduff. Macbeth is overconfident and eagerly acts out on his anger. He does not think before deciding to slaughter the innocent that have no threat against his throne. There is no guilt left inside Macbeth because he is becoming unhuman because he is desensitized to death.
Lady Macbeth dies from the guilt she felt for the domino effect of the first murder. Lady Macbeth knew that if she wasn’t so manipulative during the first murder that Macduff’s family would still be alive. Macbeth was so consumed by the demands of protecting the throne that it completely changes his nature into that of someone who doesn’t hold any meaning to life. When Macbeth hears of his wife’s death he is numb to the fact that he has lost her. He apathetically states, “Out, out brief candle” which makes the death of his wife seem merely trivial. He sees life now as, “ a poor player that struts and frets his hour upon the stage…signifying nothing.” Macbeth feels that life is predetermined and that nothing a person can do or say will change their destiny; in short humans are living to die. Macbeth sees no meaning behind human life which is a final account of Macbeth’s descent into evil.
Macbeth was originally a loyal kinsman and subject, but with the aid of the witches’ manipulation and Lady Macbeth’s plan to take the throne it is obvious that Macbeth was doomed from the start. The security of the throne demanded protection because of the way it was attained. Life becoming more worthless and the guilt behind each murder weakening showed Macbeth’ nature and nature itself was changed into evil. Macbeth’s lack of appreciation for life and finding no meaning in it finalized his descent into evil.
