" The tables full", " which of you has done this" Act 3, scene 4

At this time in the play, Macbeth is King of Scotland. He is having a party. After Macbeth killed Duncan, Macbeth turned around and killed his good friend Banquo. He kills Banquo because the witches tell Banquo that he will be the father of kings. Macbeth cant deal with the idea that after he is dead Banquo's son's will take the throne. So Macbeth kils Banquo and tries to kill his son Fleance but is unsuccessful. At his party Macbeth believes he see's the ghost of Banquo sitting in his chair. This part of the play shows that Macbeth is having guilty thoughts about killing Banquo. Not killing Fleance has changed the fate of the play.
