Is the death of Romeo and Juliet due to fate or flaws? Do you know any quotes from the text that support either side?
The phrase "star-cross'd" would refer to the heavens, like an astrological prediction. However, I think the wonder of the play is the way that they die due to both. If they didn't love so passionately, if Juliet had married Paris, if Romeo had been true to Rosalind, if they hadn't gone so crazy with grief at the end (all of which would be flaws), they'd be alive, but those flaws kill them because of the specific situation.
