Injustice In Shakespeare's Romeo And Juliet

In a social commentary lense, in the play, Romeo and Juliet by William Shakespeare, the most significant scene is in 5.2, when the letter Friar Lawrence writes to Romeo is not delivered, because it shapes the events that end the feud between the Capulets and the Montagues. When Friar John comes back from his supposed trip to Mantua to deliver a letter to Romeo, he comes back and tells Friar Lawrence:
Going to find a barefoot brother out,
One of our order, to associate me,
Here in this city visiting the sick,
And finding him, the searchers of the town,
Suspecting that we both were in a house
Where the infectious pestilence did reign,
Sealed up the doors and would not let us forth.
So that my speed to Mantua there was stayed (5.2.5-12).
Friar John’s bad news hints that Romeo did not receive Lawrence’s letter that states that Juliet is not dead, which shaped the event when Balthasar told Romeo, in 5.1, that Juliet died, causing Romeo to be worried sick and find a way to kill himself by buying poison just to be with her, which ends up causing their families to end their destructive feud. Next, after Friar Lawrence finds out that Friar John didn’t deliver his letter to Romeo, he says:
However, little does he know, Romeo is already on his way to kill himself with a vile of poison he got from the apothecary in Mantua, to be dead with her. In conclusion, the most significant scene throughout the entire play, is where Friar Lawrence’s letter notify Romeo that Juliet is not actually dead, doesn’t get delivered to Romeo leading up to the tragic death of Romeo and Juliet which causes the Capulets and the Montagues to end their feud because they suspected that it is their destructive feud that caused their children to die and caused the deaths of Tybalt, Mercutio, and
