"From forth the fatal loins of these two foes
A pair of star-cross'd lovers take their life." (Prologue line 5-6)
Many characters believe they are controlled by the stars. The plot stresses the power fate has on Romeo and Juliet's lives. Although the characters foresee the future, they are not able to change the outcome. Even the power of love is not able to change their fate. Romeo and Juliet are destined to die and end their parents' feud.
The characters make references to the stars and express premonitions of doom. Romeo becomes a pitiful puppet in the hands of fate when he says:
"I fear too early; for my mind misgives
Some consequence yet handing in the stars
Shall bitterly begin his fearful date...
By some vile forfeit of untimely death." (Act 1 Sc 5 Line 106)
Proving that Romeo feels uneasy about going to the Capulet party but he does not follow his instincts. Even Friar Lawrence tries to reassure himself with prayers, yet he notes that:
"These violent delights have violent ends."(Act2 Sc 6 Line 9)
As Romeo leaves for exile, Juliet looks down from her window and murmurs:
"Methinks I see thee, now thou are so low,
As one dead in the bottom of a tomb." (Act 3 Sc 5 Line 55)
Juliet has a vision of Romeo dead in a tomb, which is where Romeo ends up in the end of the play. Hence, the characters have dreams and omens of what fate has in store for them.
Several preplanned events influence the destiny of Romeo and Juliet. If Romeo and Benvolio had not bumped into the Capulet servant would was illiterate in Act Scene they would have found out about the party or that Rosaline was going to be there. Romeo and Juliet may not have met. Romeo did not receive the message from the Friar John
