The name Romeo, in popular culture, has become nearly synonymous with “lover.” Romeo, in Romeo and Juliet, does indeed experience a love of such purity and passion that he kills himself when he believes that the object of his love, Juliet, has died. The power of Romeo's love, however, often obscures a clear vision of Romeo’s character, which is far more complex.

Even Romeo’s relation to love is not so simple. At the beginning of the play, Romeo pines for Rosaline, proclaiming her the paragon of women and despairing at her indifference toward him. Taken together, Romeo’s Rosaline-induced histrionics seem rather juvenile. Romeo is a great reader of love poetry, and the portrayal of his love for Rosaline suggests he is trying to re-create the feelings that he has read about. After Romeo first kisses Juliet, she tells him, “you kiss by th’ book,” meaning that he kisses according to the rules, and implying that while proficient, his kissing lacks originality (1.5.107). In reference to Rosaline, it seems, Romeo loves by the book. Rosaline, of course, slips from Romeo’s mind at first sight of Juliet.

But Juliet is no mere replacement for Rosaline. The love she shares with Romeo is far deeper, more authentic, and unique than the clichéd puppy love felt for Rosaline. Romeo’s love matures over the course of the play from the shallow desire to be in love to a profound and intense passion. One must ascribe Romeo’s development at least in part to Juliet. Her level-headed observations, such as the one about Romeo’s kissing, seem just the thing to snap from his superficial idea of love and to inspire him to begin to speak some of the most beautiful and intense love poetry ever written.

Yet Romeo’s deep capacity for love is merely a part of his larger capacity for intense feelings of all kinds. Put another way, it is possible to describe Romeo as lacking the capacity for moderation. Love compels Romeo to sneak into the garden of his enemy’s daughter, risking death simply to catch a glimpse of her. Anger compels Romeo to kill his wife’s cousin in a reckless duel to avenge the death of his friend. Despair compels Romeo to suicide upon hearing of Juliet’s death. Such extreme behavior dominates Romeo’s character throughout the play and contributes to the ultimate tragedy that befalls the lovers. Had Romeo restrained himself from killing Tybalt, or waited even one day before killing himself after hearing the news of Juliet’s death, matters might have ended happily. Of course, though, if Romeo hadn't had such depths of feeling, the love he shared with Juliet would never have existed in the first place.

Among his friends, especially while bantering with Mercutio, Romeo shows glimpses of his social persona. He is intelligent, quick-witted, fond of verbal jousting (particularly about sex), loyal, and unafraid of danger.
