Why do lord Capulet and lord Montague stop their feud at the end of the play?

Answer 1

I think that in one point in the story, a fight between the two houses caused some innocent citizens to die, so the Prince finally said that next time there was a fight, the people responsible would be put to death.

Answer 2

After lord Capulet lost his daughter and lord Montague his son, they realized that no more lives should be taking from this aging feud. So lord Capulet promised to make a monument of Romeo and Montague would make a monument of Juliet.

Answer 3

They shouldn't do it because it is wrong. It disturbs the streets, causes property damage, hurts people and eventually kills them. And it accomplishes nothing. It is pathetic that it takes the deaths of Romeo and Juliet to make them realize this.

Answer 4

The Prince says "See what a scourge is laid upon your hate, that heaven finds means to kill your joys with love." The Prince does not say that they caused the deaths but that the deaths are a punishment from God for their evil feud. He also says that he himself has been punished for being lenient by the deaths of Mercutio and Paris. "All are punished!"

It's not clear that Capulet wholly buys this line but he is deeply hurt at this point not so much by the death of his daughter and only child who he mourns deeply and tragically in Act IV when he thinks her to be dead ("Oh child, oh child! My soul and not my child! Dead art thou--alack, my child is dead, and with my child my joys are buried.") but with the knowledge that she was married, and married to a good man, "a virtuous and well-governed youth" as he called him in Act I. He is thinking about Romeo and that Montague is suffering the same deep and tragic sorrow for the loss of his only child. His sympathy makes him call his former enemy "brother Montague" because they are brothers in sorrow. Then you can tell that he is thinking about the fact that their children were married and that Romeo was his son-in-law by talking about the "jointure", the money that should be settled by a husband on his bride. Perhaps he senses that the only jointure that would have pleased Juliet is peace between the families, so he offers that, to honour her.
