Who Is Responsible For Mercutio's Death

In Shakespeare's Romeo and Juliet, Act 3, Scene 1, Mercutio dies. The Capulets and the Montagues are both responsible for his death because of the longstanding family feud, Mercutio being in the wrong place at the wrong time, and the relationship between Romeo and Juliet. {{Good job!}}

The longstanding family feud between the Capulets and the Montagues caused a lot of fighting between the two families for years. Mercutio was not a Capulet or Montague, but a friend of Romeo who was a Montague. So by association, Mercutio is an enemy to the Capulets. When Mercutio was killed, it was in a fight that was intended for Romeo by Tybalt, a member of the Capulet family.{{Incorporate details or textual support to show this evidence, rather than a broad description.

This is when Mercutio, who couldn't back down from a fight, steps in for Romeo because they are good friends. Mercutio is upset with Romeo's lack of awareness and lack of aggression. Romeo's mind is too busy thinking about Juliet and their marriage. This supports the example of Mercutio being in the wrong place at the wrong time. {{Incorporate details or textual support to show this evidence, rather than a broad description.

The relationship between Romeo and Juliet caused Romeo to be very distracted. He was unaware that Tybalt wanted to fight him. Romeo happened to come across Tybalt and Mercutio as they began to duel. He stepped in, but the sword went under his arm and stabbed Mercutio, causing him to die.{{Incorporate details or textual support to show this evidence, rather than a broad description.
