Question

Tybalt is portrayed as a villain in the play, and yet his death is not a positive event. Why is Tybalt’s death bad for Romeo and Juliet?

Answer 1

I found this:
For two reasons: first because it results in Romeo getting banished and thus keeping the lovers apart. And second, because Tybalt was the son of Lady Capulet's brother, which means that she is insanely vengeful towards Romeo.The plan was, that once Romeo and Juliet's marriage is consummated (and so cannot be annulled), they would present it to the parents as a fait accompli. But after Tybalt's death, the chances of Lady C accepting her daughter's marriage to Romeo are pretty remote. Already in the play she is plotting his death. It would be clear to the Capulets that the solution to this distasteful marriage would be to make Juliet a widow as soon as possible.
