"(I, VII, l.42-48) Making Macbeth feel bad and not strong enough she changed his mind. He was now ready to kill Duncan. When she became the queen of Scotland something that she never thought would happen happened. She could not sleep because she could not stop dreaming about Duncan and his body that was scattered with blood. She would keep on washing her hands so the blood would disappear but it was not helping her because soon after she died. Banquo is Macbeth's former best friend who knows about the witches and knows that there is something-weird going on. He is an honest and loyal friend that served the king. When he realised that Macbeth killed Duncan he knew that it would be his turn. "Thou hast it now: king, Cawdor, Glamis, all. As The weird women promised; and I fear thou play'dst Most foully for't yet it was said. It should not stand In thy posterity"(III, I, l.1-4) Banquo realised that Macbeth wants to kill him as well, the witches said that he would be the father to the line of kings. That means that Macbeth could not be king for a long time, so the only thing that Macbeth could do is kill him and his son. Macbeth killed Banquo but his son Fleance escaped and that is why Banquos murder led to Macbeth's downfall. Fleance would live to tell everyone what happened. After Banquo's murder Macbeth would forever be haunted by his soul and Macbeth would never rest in peace. Mucduff was another of the king's loyal friends who knew Macbeth was the murderer. Macbeth killed his children, his wife and destroyed his life. The only thing that was left for him to do was get revenge. He said that if he doesn't kill Macbeth he will not be able to sleep and he will never rest in peace. " If thou be'st slain and with no stroke Of mine, my wife and children ghosts will Haunt me still"(V, I, l.20-22) Revenge was the only thing that Macduff had on his mind. He could not rest in peace if he did not kill Macbeth.
