I doubt that it is Act V, scene ii.  Macbeth does not appear in this scene.  It is only a page long and is often cut from the staged play.

Macbeth Act III, scene ii reveals Macbeth's cruelty and cunning as a leader.  It continues the motifs of betrayal and treachery, as Macbeth decides to kill his best friend, Banquo.

In the scene the Macbeths are King and Queen.  Power has gone to Macbeth's head, and he continues the blood-letting: his first order of business as King is to kill Banquo and his son.  Their murders are a means of protecting his power and stranglehold on the crown.  He attempts to defy fate and the witches' prophecies (which said that Banquo would be greater than Macbeth and the father of kings.).

This scene also shows the division of labor in the Macbeths' marriage.  Earlier, in Act I, Lady Macbeth devised the plan to kill Duncan, and Macbeth carried it out.  Here, Macbeth decides not to consult Lady Macbeth in Banquo's murder.  He wants to surprise her with the news later.  This separation between the two spells the beginning of the end.  Together, they were a cruel force to be reckoned with.  Apart, they are vulnerable.  Sure enough, Lady Macbeth will soon descend into madness shortly after this.
