While Juliet possesses the tragic impulsiveness of Romeo in Shakespeare’s play, she has the sterling traits of caution and loyalty. In addition, she is of a passionate nature, which while good, does at times work to her detriment.
In the first act when her Lady Capulet asks Juliet to consider Paris as a husband, Juliet wisely exerts, caution; she merely promises to look at the man:
I'll look to like, if looking liking move;
But no more deep will I endart mine eye
Than your consent gives strength to make it fly.
She also urges Romeo to not to swear his love by something so fickle as the moon:
O, swear not by the moon, the inconstant moon,
That monthly changes in her circled orb,
Lest that thy love prove likewise variable. (2.2.113-115)
Do not swear at all;
Or if thou wilt, swear by thy gracious self,
Which is the god of my idolatry,
And I'll believe thee. (2.2.118-120
Then, in last scene of this act, Juliet asks Romeo not to kiss her, but exert more restraint and merely touch hands; she is seemingly wary of rushing into a relationship with him:
Good pilgrim, you do wrong your hand too much,
Which mannerly devotion shows in this;
For saints have hands that pilgrims’ hands do touch,
And palm to palm is holy palmers’ kiss. (105)
After the Nurse returns from the streets of Verona where she has learned of the death of Tybalt, she cries out both Tybalt’s and Romeo’s names, confusing Juliet. Finally when Juliet learns the truth, she chides the Nurse for saying “Shame come to Romeo":
Blister'd be thy tongue (95)
For such a wish! He was not born to shame.
Upon his brow shame is asham'd to sit;
For 'tis a throne where honour may be crown'd
Sole monarch of the universal earth.
O, what a beast was I to chide at him! (100)
When Lady Capulet calls Romeo a villain, Juliet says in an aside,
Villain and he be many miles asunder.
God pardon him! I do, with all my heart;
And yet no man like he doth grieve my heart. (3.2.84-86)
Finally in this scene, the Nurse urges Juliet to marry Paris even though she knows that Juliet is already married. Juliet retorts,
Ancient damnation! O most wicked fiend!
Is it more sin to wish me thus forsworn,
Or to dispraise my lord with that same tongue
Which she hath prais'd him with above compare
So many thousand times? Go, counsellor!
Thou and my bosom henceforth shall be twain.
I'll to the friar to know his remedy.
If all else fail, myself have power to die. (3.5.246-253)
Juliet displays her passionate nature in these passages:
My bounty is as boundless as the sea,
My love as deep; the more I give to thee,
The more I have, for both are infinite.
I hear some noise within. Dear love, adieu! (2.2.139-142)
O, bid me leap, rather than marry Paris,
From off the battlements of yonder tower,
Or walk in thievish ways, or bid me lurk
Where serpents are; chain me with roaring bears,
Or shut me nightly in a charnel house,
O'ercover'd quite with dead men's rattling bones,
With reeky shanks and yellow chapless skulls;
Or bid me go into a new-made grave (85)
And hide me with a dead man in his shroud —
Things that, to hear them told, have made me tremble —
And I will do it without fear or doubt,
To live an unstain'd wife to my sweet love. (4.1.78-89)
