What are the emotional problems and moral problems that exist in relationships between Romeo and Juliet and another character that lead to death to both Romeo and Juliet?
Romeo and Juliet have a violent love; it is predicated upon the turbulent emotions of Romeo. It exists amid the animosity of the Capulets and Montagues, and it ends with this same hatred.
Certainly, the love of Romeo and Juliet is a fated love between "star-crossed lovers" because of the vitriolic hatred between the Capulets and the Montagues. When the fiery Tybalt sees Romeo and his friends at the party honoring Juliet, he immediately becomes incensed.
This, by his voice, should be a montague.
Fetch me my rapier, boy. What! Dares the slave
Come hither, cover'd with an antic face,
To fleer and scorn at our solemnity?
Now by the stock and honor of my kin,
To strike him dead I hold it not a sin. (1.5.52-57)
Despite the enmity between the families, Romeo and Juliet marry, and Friar Laurence, who performs the marriage ceremony, has hopes that the union of the two young lovers will ameliorate the relationship between the feuding families. This feeling is later shared by Romeo, who, when confronted by the bellicose Tybalt, tries to intervene in the argument between Mercutio and Tybalt by telling Tybalt that he has a reason to love him. In Act III, Scene 3, he tells Tybalt that now he does "But love thee better than thou canst devise" (3.3.68). When Romeo says these words, Mercutio is incensed, thinking that Romeo is submitting to Tybalt, not knowing that Romeo has married Juliet. He draws his sword against Tybalt. Although Romeo tries to intervene, the stirring of Tybalt's wrath and the antagonistic gestures of Mercutio effect disaster as Mercutio is slain by Tybalt and, then, Romeo kills him in retaliation for Mercutio's murder.
The action of this scene leads to Romeo's banishment, Juliet's dilemma as she is told she must marry Paris, her hopelessness, Romeo's dismay and desperation when he learns that Juliet is "buried" in the Capulet tomb, and Romeo and Juliet's final acts of despair over the loss of each other.
