preparing for war
"The king" here is Macbeth. He is exasperated by the attempts of Malcolm to raise an army against him. Therefore he "prepares for some attempt of war", and what does it mean to prepare for war? To raise an army, train and arm soldiers, that sort of thing.
Lady Macbeth and Macbeth attempted to do the murder. They will be punished for what they attempted to do even if they didnt succeed
Lady Macbeth questions Macbeth to provoke him into taking action. She challenges his masculinity and questions his resolve in order to manipulate him into following through with their plan to kill King Duncan.
young siward was slain in the attempt to murder macbeth.
The assassins in Macbeth kill Banquo, a close friend of Macbeth, and attempt to kill Fleance, Banquo's son. They are hired by Macbeth to eliminate any potential threats to his throne, as Banquo's descendants are prophesied to inherit the kingdom.
The prophecy given to Banquo by the witches in Shakespeare's Macbeth is that he will father a line of kings, though he himself will never be king. This prophecy ultimately leads to Banquo's murder by Macbeth in an attempt to prevent his descendants from taking the throne.
Macbeth doesn't really have a conflict with them. Banquo suspects Macbeth of killing Duncan, but isn't saying anything. Macbeth is annoyed by the witches' prediction that his children will not succeed him (Does he have children? The way things are going between him and his wife, is it likely that he will?) but that Banquo's decendants will. He is jealous. Macbeth's murder of Banquo and attempt on Fleance's life are an attempt to prove to himself that his future is not controlled, and that he is free. He wants to know that he became king because of what he did, not some inexorable fate. When the murderers fail to kill Fleance, he says, "Then comes my fit again!". He has not proven that he is free. The witches' predictions about Banquo can come true. Maybe it is all a matter of fate after all.
Ignorance leads to killing Banquo in Shakespeare's play "Macbeth" because Macbeth believes that Banquo's descendants pose a threat to his own reign. Macbeth is misled by the witches' prophecies and allows his fears and ambition to cloud his judgment, leading him to order Banquo's murder in an attempt to prevent the realization of the witches' predictions.
The "Thane of Cawdor" is executed in Shakespeare's Macbeth because he is found guilty of treason and betrayal, having betrayed King Duncan by aligning with the Norwegian invaders. His execution serves as a warning to others who may attempt to deceive or betray the king. The title of Thane of Cawdor is then awarded to Macbeth for his valor and loyalty in battle.
Macbeth sends murderers to kill Macduff's family in an attempt to eliminate any potential threats to his own power. This ruthless act solidifies Macbeth's descent into tyranny and cruelty, as he seeks to maintain his position on the throne at any cost. The murder of Macduff's family ultimately leads to Macduff seeking revenge against Macbeth, contributing to his downfall.
After committing the first murder himself, Macbeth sends out hired murderers to deal with Banquo and with Macduff's family. As a result, he does not kill the people he is really worried about: Macduff and Fleance (since it is Banquo's children and not Banquo he is to worry about)
The final moment of the play, after Malcolm's speech, could bring out three different interpretations: (1) that there will now be peace and harmony in Scotland; (2) that Malcolm will not be strong enough to prevent civil war from breaking out; (3) that Malcolm will himself prove to be a tyrant. Also one of William Shakespeare's signature ways to end his plays was to have a character of social significance, not necessarily one that was significant in the plot
