While it is difficult to assess whether Paris genuinely loves Juliet since the sequence of Romeo and Juliet is a mere three days, there are, however, indications that Paris is passionate about Juliet Capulet. In Act I, for instance, he attempts to persuade Lord Capulet to permit him to marry Juliet, but is put off by Capulet, who replies that she is too young. Paris argues, "Younger than she are happy mothers made" (1.2.13), indicating that he truly desires Juliet. Later in Scene 4, Lady Capulet asks Juliet to look upon Paris and see if she can love him, so, evidently, Capulet has mentioned the suit of Paris to his wife, and is, therefore, considering the marriage.
It is not until Act IV that Paris reappears as he speaks with Friar Laurence about performing the marriage ceremony for Juliet and him. He tells the priest that he is concerned about her, and Juliet's father, too, "counts it dangerous" that she grieve so much. Therefore, Capulet now wishes to hasten the marriage. When Juliet enters the friar's cell, Paris speaks lovingly to her, "Poor soul, thy face is much abused in tears" (4.1.30). Juliet, however, is unresponsive and wishes to make confession to the priest. So, Paris leaves, but kisses her.
Greater indications of Paris's love for Juliet occur at the end of Act IV when he arrives at the Capulet home in anticipation of his marriage to Juliet. Dismayed at Lord Capulet's face, Paris says,
Have I thought long to see this morning's face
And doth it give me such a sight as this? (4.5.44-45)
Hearing from the Nurse that Juliet has died, Paris exclaims in what seems genuine emotion,Beguil'd, divorced, wronged, spited, slain!
Most detestable Death, by thee beguil'd,
By cruel cruel thee quite overthrown!
O love! O life! not life, but love in death! (4.5.58-61)
In his anguish, Paris hurries to the tomb of Juliet, arriving there before anyone else. As he enters, Paris utters poignant words,
Sweet flower, with flowers thy bridal bed I strew
(O woe! thy canopy is dust and stones)
Which with sweet water nightly I will dew;
Or, wanting that, with tears distill'd by moans.
The obsequies that I for thee will keep
Nightly shall be to strew thy grave and weep (5.3.12-17)
Shortly after Paris expresses his loving grief, Romeo arrives; Paris recognizes him as Tybalt's murderer and assumes that Romeo has come to commit some "villainous shame to the dead bodies." He attempts to stop Romeo, saying,
I do defy thy conjuration
And apprehend thee for a felon here. (5.3.68-69)
Then, when Romeo stabs him with his sword, Paris's dying words are a request to be lain with Juliet, eager to marry you,
O, I am slain! If thou be merciful,
Open the tomb, lay me with Juliet. (5.3.72-73)
Desirous of marrying Juliet, dismayed at her grief and worried about her, grief-stricken himself at her apparent death, defensive of her body and memory, and devoted to her even in death, Paris gives indication, indeed, of being passionate about Juliet.
