In the last act, both the Capulets and Montagues realize the error of their ways and regret how insensitive they were to the needs of their children. But first, the Prince admonishes them all:
See what a scourage is laid upon your hate,
That heaven finds means to kill your joys with love ; ' And I, for winding at your discords too,
Have lost a brace of kinsmen. All are punished." (5.3. 290-294).
Finally, the parents get it. Capulet reaches out to his former enemy:
"O brother Montague, give me thy hand .
This is my daughter's jointure, for no more
Can I demand." (5.3.295-297)
For his part, Montague replies,
"But I can give thee more,
For I will raise her statue in pure gold,
That whiles Verona by that name is known, There shall no figure at such rate be set
As taht of true and faithful Juliet." (5.3.298-301).
Of course, their epiphany comes too late to save their children, but at least they now have the sense to stop their needless fighting.
