The three witches' predictions came true, for Banquo and for Macbeth [d. August 15, 1057]. For Banquo, the witches predicted that he wouldn't lead as fortunate or powerful a life as Macbeth. He didn't receive anything from King Duncan I [d. August 14, 1040] for having fought as bravely as his friend and fellow General Macbeth against invading Norwegians and treacherous Scotsmen. He didn't lead a charmed life, because he was killed by three murderers who had been hired by Macbeth. But the witches had said that Banquo's family line ultimately would occupy the Scottish throne for generations. According to legend, Banquo's son Fleance escaped to Wales, to marry Nesta verch Gruffydd, the daughter of Gruffydd ap Llywelan [c. 1007-August 5, 1063], the last native Prince of Wales; and Aldgyth/Edith [d. after 1070], who took as her second husband, King Harold II [c. 1022-October 14, 1066] of England. Aldgyth was the daughter of Aelfgar [d. c. 1062], Earl of Mercia; and the granddaughter of Leofric [d. August 31 or September 30, 1057], Earl of Mercia and husband of Godgifu [fl. 1040-1080], who became known throughout history as Lady Godiva. Considering that her background mixed with royalty, Nesta's family tree was preserved better than most. And according to genealogical and historical records, Nesta was married only once, to Osbern FitzRichard. Supposedly, she and Fleance had a son, Walter, who went back to Scotland. There he became the Royal Steward to the Kings. Eventually, he married into the line and supposedly became the ancestor of the contemporary of William Shakespeare [Baptized April 26, 1564-April 23, 1616], King James [June 19, 1566-March 27, 1625] I of England and Ireland and VI of Scotland. But, once again, neither the existence nor the impact of Banquo and his son Fleance appeared to be born out in genealogical and historical records. Likewise did the witches' predictions come true for Macbeth. He already was Thane of Glamis. He became Thane of Cawdor with the execution of the disgraced previous title holder and with the assignment of title and possessions to him. He also became King of Scotland. But the witches predicted that Macbeth's rule would be secure as long as Birnam Wood didn't move to Dunsinane Castle, and as long as he didn't come across any man not born of woman. The subsequent King Malcolm III [d. November 13, 1093] had his combined forces of Englishmen and Scotsmen pluck and carry boughs from Birnam Wood. The effect was of a moving forest. The man whom Malcolm had approved for the murder of Macbeth was Macduff, who had been delivered by Caesarian section from a dead mother. It could be said that he hadn't been born of a woman. And the witches rightly had warned Macbeth to beware of Macduff.
None of the predictions made to Banquo come true in the course of the play. The first prediction which comes true is that Macbeth will become king (He is already Thane of Cawdor when they meet the witches, so that is not a prediction.)
She helps Macbeth out by tricking him into killing the king. :P
The witches' prediction that Macbeth will become the Thane of Cawdor has come true, as he receives this title in Act 1. However, their prediction that Macbeth will become King has not yet been fulfilled at this point in the play.
The witches predict that Macbeth should be wary of Macduff, as he is a potential threat. This comes true when Macduff leads an army to overthrow Macbeth. They also predict that Macbeth will not be defeated until Birnam Wood comes to Dunsinane. This comes true when Malcolm's army uses tree branches from Birnam Wood as camouflage to approach Macbeth's castle.
The witches predict that Macbeth will be king and how he will fall. These predictions cause Macbeth to dedicate his life to following the witches predictions, doing whatever it takes to make them come true, or to avoid them.
Macbeth is inclined to wait and watch the prophecy come true by itself. Lady M sees the prediction as a call to action, commanding her to incite Macbeth to murder the king.
The Prophecy says Macbeth will be king. Duncan is king. Macbeth cannot be king while Duncan is king. Duncan will not be king when he is dead. Therefore, make Duncan dead.
When Macbeth saw that the witches second set of predictions were coming true, Macbeth lost it.
True. In Shakespeare's play "Macbeth," the character Macbeth expresses envy towards King Duncan when he hears about the prophecy that Banquo's sons will be kings. Macbeth feels this sense of envy and ambition that drives him to commit regicide in order to fulfill the prophecy.
After hearing the witches' prophecy, Macbeth struggles with conflicting desires for power and the moral consequences of achieving it. He grapples with his ambition to become king while also battling guilt and fear about the actions he might have to take to fulfill the prophecy. This conflict drives Macbeth to make choices that lead to his downfall.
The conflict that rages in Macbeth after he hears the witches prophecy is if he has to take some action to make the prediction true or if it's all up to fate. When he hears Duncan say that Malcolm is to become the next king he knows he has to take action for the prophecy to come true.
The three witches predict that Macbeth will become the Thane of Cawdor and then the King of Scotland. They also predict that Banquo's descendants will inherit the throne, sparking Macbeth's ambition and actions to make the prophecies come true.
