Influence of Witches and Lady MacbethThe last person you would expect to encourage you to commit a crime would be your wife. Macbeth is motivated by his wife and three witches and becomes progressively more ruthless, wicked, and murderous as the play progresses. Lady Macbeth is first introduced in Act 1 Scene 5: reading a letter received from Macbeth describing the encounter with the witches and the prophecies they gave him. Lady Macbeth is very ambitious; believes that Macbeth is too kind and loyal to take the necessary steps to become king. "Yet I fear your nature; it is too full of the milk of human kindness to take the nearest path." Lady Macbeth uses Macbeth's weaknesses to convince him to kill King Duncan: she challenges his manhood "When you dared to do it, then you were a man." “You esteem the ornament of life and live cowardly in your own esteem.” She tries to make him feel guilty: Macbeth promised to kill Duncan, he changes his mind. "What a beast was not, so it made me discontinue this business." In Macbeth, witches are shown to be evil, conniving, and cruel. "Here I have a pilot's thumb, destroyed, because he flew home." The witches play a major role in convincing Macbeth to kill Duncan. They give Macbeth and Bonquo ​​three prophecies: "Hail to you Macbeth, thane of Cawdor" "Hail to all, Macbeth who will be king from now on" "You will have kings, even if there are none. » Bonquo ​​does not take these prophecies seriously, but Macbeth shows some ambition for power. “If chance wants me to be king, well, chance will crown me.” Macbeth becomes more and more dependent on witches. In Act 4, Scene 1, Macbeth returns to the strange sisters, demanding what the future holds for them. The Witches gave him three prophecies: "Macbeth! Macbeth! Macbeth! Watch out Macduff, watch out for the thane of Fife." “None of the women born shall harm Macbeth” “Macbeth shall never be defeated till Great Birnam wood unto the high hill of Dunsinane.” As the play progresses, Macbeth takes a turn for the worse. He becomes more ruthless, evil and murderous. After killing Duncan, Macbeth feels remorse and guilt. "To know my deed, it's better not to know it myself. Wake Duncan by knocking! I wish you could." Not being able to return to Duncan's room and place the knives is a show of weakness and remorse..
