The biggest hate and the play comes in the form of a deadly feud between the Montagu’s and the Capulet’s.They hate between the two families ultimately lead to the deaths of Romeo, Juliet and Tybalt.
The great love story of Romeo and Juliet finding each other even with all of the obstacles in their path and ultimately bringing the two families together with their untimely deaths.
In the Prologue to Romeo and Juliet, the Chorus tells us of an "ancient grudge" between two households of equal dignity that has broken out into a "new mutiny" that will cause blood to flow in the streets of Verona and will ultimately result in the deaths of the "star-cross'd lovers." The Chorus points to the heads of these two families as the source of the strife at hand, the rage of their parents causing the deaths of their children.
There is ample evidence of both fate and free will in the play, and the presence of both greatly affects the interpretation of the plot and the characters.
Fate as a dominating force is evident from the very beginning of the play.
As Sampson and Gregory square off against Abram and Balthasar, the vulgar obscenities and gestures which they exchange undercut any sense of real danger.
The interplay among these underlings is stylized and restrained; before any threshold is crossed, Samson checks with Gregory about whether the law is on their side if they assent to an implied challenge.
Two of the fairest stars in heaven, having some business, do entreat her eyes to twinkle in their spears till they return allows the audience to see the depth of Romeo’s love as he compares Juliet to of God in the sky. There is so much hatred between the Montagu’s and the caplets it threatens to destroy the social stability of the city of Verona.
Romeo says, “By a name I know not how to tell thee who I am: my name, dear saint, is hateful to myself.” In this quote you see that Romeo understands the hate Juliet’s family will feel towards him based solely on his last name.
That being so, the cause of the ongoing mutiny that is played out before us does not stem solely from strong parental domination but also from the weak authority of the state as embodied in Prince Escalus.
The play moves directly from the Prologue to a lower case example of the mutiny as a confrontation unfolds between servants of the Capulet and Montague households.
