Juliet Capulet at the beginning of Romeo and Juliet is a very different person than Juliet Capulet Montague, who emerges toward the end of the tragedy. Joseph Bryant makes an accurate point when he says that Juliet is "arrogantly eager to outdo her elders (in the beginning of the play.)" This rebelliousness is evident when Juliet says, "Or, if thou wilt not, be but sworn my love,/ And I’ll no longer be a Capulet." This quote is symbolic of Juliet’s naïve rebelliousness against her parents. She is willing to go against her family in order to be with Romeo, but she is unaware of the consequences. Juliet’s naïve nature is further exposed when she inquires "What’s in a name?" referring to the feud between the Montagues and Capulets. The fact is that both names represent the families’ hatred of each other, and changing the name cannot change the hatred. (good focus on the "name" motif--you could focus on this for your whole response!) A transformation occurs when Romeo is banished and Juliet finds out she must marry Paris, Juliet’s naïve rebelliousness must die and turn into a knowledgeable fear that she may never be with her beloved Romeo again. confusing sentence--runs on

The transformation of Juliet is complete when she "learns to mix courage with innocence." When Juliet finds out she is to marry Paris, even the nurse says, "I think you are happy in this second match," in other words, "I think you are better off with Paris." Realizing that she no longer has the support of anyone in her household, Juliet must be courageous on her own; she can no longer rely on the nurse’s support. Juliet comments on the nurse after she suggests that Juliet marry Paris by saying, "Ancient damnation! O most wicked fiend." The Capulets’ abandonment of Juliet parallels fate’s abandonment of Romeo and Juliet. Fate brought Romeo and Juliet together to love each other, and then leaves the two to fend for themselves in a world of hate. In this, Juliet is innocent with respect to the fact that she has done nothing to deserve being thrown amidst a hateful world. However Juliet is now well aware of the hatred present in her world. Now, what Capulet and Lady Capulet call rebellion is really Juliet trying to save her love with Romeo. Juliet realizes that simply changing one’s name cannot change a world of hate. Juliet has matured, she can see that the world around her is not going to let her be with Romeo easily.

Juliet’s final attempt to save the marriage of her and Romeo proves to be a fatal one; she falls victim to the world. She stares ugly reality in the face when she addresses her mother and the nurse as they say goodnight to her, saying, "Farewell! God knows when we shall meet again." Here, Juliet is acknowledging that she cannot unite two worlds: the world of Juliet and Romeo and the world of Juliet and her family. Then, she drinks the potion that is fatal in a way. It only puts her to sleep, but in the end results in the death of Juliet. Juliet’s fake death not only foreshadows her and Romeo’s actual deaths, but it also symbolizes the death of any idea of ever being with Romeo again. Juliet falls victim to the world of conflict, where the Capulets would never accept her marriage to Romeo. Juliet’s battle against this conflict illustrates her courageous nature.

Juliet’s conflict with a world of hatred proves that she is the most courageous character in the play. This same conflict which proves Juliet’s courage also results in the loss of her life. Fate brings Romeo and Juliet together in this play and then abandons them. Ironically, in the end fate brings the two together permanently.
This is a strong response, if a bit too long and complex.  The focus on "names" is excellent, as is your treatment of "fate" in the play.  And I think you're quite right, that J's response to these two motifs shows her great courage.  Overall a good reading.  9.0
