I have always thought it was very sad, but I always allow myself a bit of anger as well. Why anger? Anger that they had no one to turn to because of the horrible feud! At least some avoidable and thoughtless teenage angst and desperation can be found in both of the main characters. *sigh* I can't help but feel that if they each had a special mentor, one not connected to the Church perhaps, like Friar Laurence, things wouldn't have happened as they did. Except for the Friar, these two seemed to have no where to turn. The parents were distant and the friends were always looking for a fight (and were teens themselves). If only Verona had a Boys and Girls Club back then (or a YMCA/YWCA)!
This question is really about your personal opinion. There is no wrong or right answer.
Personally, I thought that their death, although romantic, was very avoidable. First of all, their marriage after only a day of knowing each other was completely juvenile, impulsive, and irresponsible. I also don't believe that people can fall in love at first sight, and I see their "love" as nothing more than sexual attraction.
Their death, however, was not completely in vain in my opinion. The Capulet/Montague feud dies with Romeo and Juliet. Upon seeing the dead couple, the prince shames the two families by saying:
See what a scourge is laid upon your hate,
That heaven finds means to kill your joys with love!
At this, Capulet responds:
O brother Montague, give me thy hand.
This is my daughter's jointure, for no more
Can I demand.
Montague agrees, and the long feud is ended, leaving the reader with some consolation.
It is extremely tragic that two young lives should be lost in this way. There is no way their loss can be viewed as a worthy sacrifice for the good of the warring families. Words should heal the wounds not lives, particularly young innocent lives like those of Romeo and Juliet. It was an utterly unfortunate event that could have been avoided and should not be glamourised or romanticised. Youth suicide is not something to be admired or vindicated even if it does make good theatre.
I think it was stupid. First of all if she would of just ran away with Romeo to Mantua insted of listening to Friar Laurence in the first place non of this would of happened. She had sooo many more opportunites then just going to Friar Laurence. And second of all Friar Laurence gave her the most complicated plan on rejoining Juliet with Romeo. And thirdly if you've read the book and watched both movies (particularly the remake) once Juliet wakes up Romeo has already drank the posion. He's still alive and she's watching him suffer! If he would of waited just a few more minutes she would of awaken and they both would of lived.
