During the battle between Laertes and Hamlet, Gertrude is accidentally killed along the process. Due to this disastrous revenge, Hamlet kills Claudius knowing that he is avenging Hamlet Sr. Without revenge, the play wouldn't have as much as a bloody and a dramatic end, considering that the deaths in the end are to a certain extent, caused by this strong desire for revenge. This drive for revenge is what led Hamlet to act as though he is ‘mad’, possibly even turning mad during the process. This led to the death of many, including Polonius. As a result, Hamlet, seeks revenge on Claudius for the brutal murder of his father. For example, Hamlet's quest for revenge is the main plot, but Laertes also seeks revenge for the murder of his father, Polonius, by Hamlet and Fortinbras brings his armies into Denmark to avenge the death of his father at the hands of the now dead king. There is 3 main revenge plots intertwined in this play. The plot itself partly focuses on the revenge of a few characters. At the end, though, when he is dying, Laertes tells the truth about his plot, and lays the blame on the King.Revenge plays a significant role when it comes to the plot development throughout the play. Then the fencing match begins, and Laertes can't find a way to touch Hamlet except by cheating. Thus Laertes more or less accepts the apology. Hamlet explains that he only did it because he was "mad." Laertes replies, "I am satisfied in nature, / Whose motive, in this case, should stir me most / To my revenge: but in my terms of honour / I stand aloof" (5.2.244-247). Later in the scene Hamlet more or less apologizes for the "wrong" that he has done Laertes, which is presumably killing Polonius, although Polonius is not mentioned. Thus, in the last scene of the play, Hamlet speaks of the fact that both he and Laertes have lost their fathers. "I am very sorry, good Horatio, / That to Laertes I forgot myself / For, by the image of my cause, I see / The portraiture of his: I'll court his favours" (5.2.75-78).
Moments later, Hamlet will become enraged with Laertes because he believes that Laertes' grief for Ophelia is melodramatic.
"That is Laertes, a very noble youth" (5.1.224), says Hamlet to Horatio, as Ophelia's funeral procession enters. The King takes a great deal of trouble to get Laertes committed to the plot, and so this is the scene which tells us the most about Laertes' character. "Now must your conscience my acquittance seal, / And you must put me in your heart for friend" (4.7.1-2), says the King to Laertes, in the scene in which they plot the death of Hamlet. Then Ophelia returns, and Laertes mourns his sister's madness. A little later in the scene Laertes come bursting in, demanding revenge for his father's death. "My brother shall know of it" (4.5.70), says mad Ophelia after saying "I cannot choose but weep, to think they should lay him i' the cold ground," which probably refers to her father. But Reynaldo is not supposed to say anything that would "dishonor" Laertes. He suspects that he is "wild" and he wants Reynaldo to find Laertes' friends and say that he's heard certain things about Laertes, so that Reynaldo can see the friends' reactions. Polonius seems to be of two minds about his son. Polonius sends Reynaldo to spy on Laertes. "Give him this money and these notes, Reynaldo" (2.1.1). " (1.3.1-2) Laertes says goodbye to Ophelia and warns her against Hamlet Polonius shows up and gives Laertes a lot of good advice. "My necessaries are embark'd: farewell: / And, sister. Laertes asks the King's permission to return to France. "My dread lord, / Your leave and favor to return to France" (1.2.50-51).
