They persauded Macbeth to kill people only because they wanted to be benefited. they were selfish and not worrying that they would soon turn Macbeth into a crazed lunatic The witches delighted in chaos and toil. They did not tell Macbeth what to do but they simply showed him what can happen through their prophecies and the apparitions they showed to Macbeth. Macbeth could've been a perfect target for them to bring about this chaos. Macbeth is a strong soldier, he has killed enemies in war, and perhaps the witches knew his true nature("by the prickling of my thumb, something wicked this way comes..."). The extent of their influenced is demonstrated through their predictions, they are temptations and a form of flattery which Macbeth eventually gave into. On one hand, Lady Macbeth has the far greater influence because she is Macbeth's wife and they share a passionate relationship together. Just like the witches she flatters him, but this time it is a direct flattery and a direct temptation towards him. As far as Macbeth being changed into a diffrent person, he himself is responsible for his own actions. The final decision lies within him and this was demonstrated when he carried out the murder of King Duncan. Lady Macbeth acts as the catalyst for Macbeth. Macbeth realised that he would have to commit regicide (stars, hide your fires; let light not see my deep and black desires), but he was unwilling to do so. Lady Macbeth changes his mind by attacking his manhood, despite the brave acts he has commited as a soldier. She also flatters him shamelessly. The murder of Duncan sets Macbeth on the trail of evil, as he didn't consult his wife when he killed Banquo and Macduff's family. He didn't even care when she commited suicide. The witches represent the Three Fates in Greek Mythology. they connotate destiny, fate, etc. They delight and thrive in chaos and toil. In my opinion, the witches represent the primeval human emotions of hate and wickedness. They are all that is…
