Four slightly random questions about Romeo and Juliet?

Although regarded at the villian, Tybalt's death is not a positive event. Why was Tybalt's death bad for Romeo and Juliet?

When Juliet refuses to refuses to allow the pressure coming from her parents and the Nurse to bother her, how does this reinforce the idea that only tradgedy will result?

How does the Nurse change after the engagement is arranged between Juliet and Paris? And how does this change affect Juliet?

And finally... How does Juliet's mother's behavior when Capulet gets angry at Juliet influence the way in which readers view Lady Capulet?

Thank you for the answer. I have already read the play several times (a few for fun, and today for English Lit. class). I simply wanted to be pointed in the right direction, perhaps just the scene in which I could find my answer.

Thank you anyway. :)

Best Answer - Chosen by Asker:

Tybalt is a "favorite older cousin" of Juliet. Juliet loved him as an "older brother." How is she now to regard Romeo, the killer of her dearest relative?

The parents have arranged Juliet's marriage with Count Paris. The nurse knows that she was already married to Romeo by Friar Lawrence. This will end badly.

The nurse says, "Why not marry with the County?" This is a crude reference to Count Paris.

I don't understand your last "And finally."
