Romeo and Juliet/Tear Jerker

This isn't tragic as a story of two in-love youths made victims of a petty rivalry, it's as a story about a couple of kids throwing away their lives because of imagined feuds. So many wasted years...
Possibly even sadder than the loss of the title pair is the fate of those who remain. Here's the Nurse, Lady Capulet and Lord Capulet, who loved Juliet so much. They've just lost Tybalt, the closest thing to a child they had besides Juliet. And, having already lost Juliet once (when they thought she was dead) they have to go through the pain all over again, knowing that they could have saved her if they'd only known, knowing that their poor, extremely young daughter spent the last moments of her life in pain and heartbreak. Lord Capulet has to live with the fact that, in one of his last conversations with her, he frightened and threatened her, expressing that he wished she had never been born, and that his actions probably were what drove her to fake her own death. The Nurse was in on the marriage, but didn't know enough to save Juliet. Then there's Lord Montague, who's all alone now that his wife and his only son are dead, and poor Benvolio, who (if he's even alive) has lost his two best friends... take it all together, this might just be the saddest ending in the history of literature.

Adaptations

The French musical adaptation, particularly Roméo's song before his death:

It's over, I'm done
I wanted to know about life, now I know
I am so tired
I don't want anything but
To simply lie down, and take her hand
Put it on my heart, forget my pain

And Benvolio's song about having to tell Roméo about Juliette's death:

Yesterday, we were still
So far, so far from death
She's fallen on the village
Like a spider spinning her web.

Mercutio's death in the Baz Luhrmann version.
In the Romeo+Juliet version, Juliet's reaction after seeing Romeo die in her arms. The long pause let out by a single sob. It's powerful.
The ending to the 1968 film, And how.
