Conflict in Romeo and Juliet

I think the most important conflict thus far was the duel between Mercutio and Tybalt. In this physical conflict, Mercutio and Tybalt engage in a rapier duel in the streets of Verona. Romeo tries to stop them which results in Tybalt killing Mercutio. In his anger, Romeo challenges Tybalt to a duel and kills him. Romeo is then banished from Verona by Prince. This conflict is so important because it intensified the Capulets' and Montagues' hatred for each other. It also resulted in the death of two characters, and one of the protagonists being banished. Romeo being banished is what a lot of the novel is about, since he can no longer be in contact with Juliet. Another theme that this conflict includes is death, which is important because the play is a tragedy.

This conflict doesn't really have much significance in current times. Situations like this are extremely rare. I suppose hot-blooded murder does happen sometimes, but neither I nor no one I know has been involved in something like this, luckily.
