Lady Macduff and Young Macduff (His wife and son)
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.
Macbeth Kills Young Siward. And Duncan, and MacDonweald earlier in the play.
One set do in Banquo. Another set do in all of Macduff's family.
The boy murdered by Macbeth's assassins was Young Siward, the son of Siward, Earl of Northumberland. He was killed during the battle between Macbeth's forces and Siward's army.
Act 3 Scene 3 :)
Lady MacDuff and her children are killed in Act 4 of "Macbeth". Macbeth hires assassins to kill the MacDuff family because he fears MacDuff is plotting against him..
And then Macbeth asked Macbeth if he confronted Macbeth on killing Macbeth with Macbeth.
The three assassins that were hired by Macbeth kill Banquo as he is walking with his son to the palace for a dinner that Macbeth invited him to.
Macbeth stabbed him when he was asleep.
The Witches forecast the downfall of Macbeth and then vanish. (not killed by anyone)
Macbeth kills him because Banquo starts to work out that Macbeth killed dDuncan
In the end it is Malcolm who finally slays Macbeth. No! Rubbish! Malcolm is a useless soldier and couldn't kill Macbeth if Macbeth were tied hand and foot. It was Macduff, the man "not of woman born", who kills Macbeth.
Macbeth killed him, by hiring some murderers.
Mainly Macbeth, but I suppose his power-hungry wife as well.
He had his suspicions because the fact the Macbeth killed the servants he blamed the murder on.
