Juliet
Juliet Capulet -- her love for Romeo opened her eyes to the world. She secretly married Romeo, forsaking the marriage her parents had arranged. At any rate, her family has this hate Montagues thing to the point where the Prince is ready to kill any Capulets and Montagues unless they "Stop the Violence." In spite of all this hatred and street brawls, Juliet's love for Romeo is for him and him alone. Juliet's feelings seem divinely inspired. Her tragic death seems strangely a fulfillment of her utterly sweet regard for the brash Montague.
Lord Capulet
Capulet his need for control destroyed his life.
Capulet has so much money, he spends freely on hospitality. His daughter gets everything she wants. Well, almost everything. He was fair and open-minded enough to let Romeo attend his party. But out of concern for Juliet, he inadvertently commits a big mistake and forces Juliet into a marriage with Paris. It was a father's vain thought to think he could control Juliet with threats and physical abuse, without really listening to her. His failure was a parent's worst nightmare - his anger and inflexibility condemned his beloved daughter to death.
Lady C.
Lady Capulet -- When it mattered, she wouldn't listen. Things can fall apart so fast. Capulet's wife can testify to that. Having craved children and a big Capulet family, she has only Juliet. Her one child is nearly the sole joy of her existence. Well, maybe not.
She speaks to her daughter: Talk not to me, for I'll not speak a word, do as thou wilt, for I have done with thee. OK, is that the right thing to say to your only child when she's on her knees begging just to speak a word?
Lady Capulet really blew it and got into a co-dependency thing while her husband abused her daughter, much to his later regret.
For Lady Capulet things fall apart so fast, and she is left bereft, empty of joy and full of self-recrimination.
The cousin of Juliet
Tybalt -- ready to live, kill or die for Honor! Mercutio flames Juliet's cousin Tybalt - Mercutio: "More than Prince of Cats. Oh he's the courageous Captain of Compliments. He fights as you sing prick-song -- keeps time, distance and proportion. He rests his minim rests -- one, two and the third in your bosom. The very butcher of a silk button, a duelist, a duelist! a gentleman of the very first house, of the first and second cause.... The pox of such antic, lisping, affecting fantasticoes." Tybalt's personal side is nice enough for Juliet to genuinely mourn his loss as a friend.
For his concern with matters of honor, Tybalt can be dishonorable. And never more so than when he kills Mercutio with an underhanded blow.
