What does Laertes say is his motive in still resenting Hamlet? How has he already lost this? How does this contribute to the presentation revenge play?
In Act IV, scene 7, Laertes says he wants revenge on Hamlet because he killed Laertes' father, and because he drove Laertes' sister Ophelia mad.
This motivation fits the structure of a revenge play in itself, but Laertes also publicly pledges to take revenge on his father's killer, which fits the structure too.
