It is Mercutio who begins fighting Tybalt when Romeo refuses to engage. Mercutio's actions lead to his own death at the hands of Tybalt.
The only one I can think of is mercutio fighting Tybalt
he holds him responsible because romeo was in the middle of the fight and when tybalt stabbed mercutio, mercuito was blinded by romeo
Mercutio.
No... Tybalt stabbed Mercutio through Romeo's arm... while Romeo was trying to stop them from fighting
He dies.
Tybalt Killed Mercutio and then Romeo was so cross he decided to kill Tybalt! =) x
Romeo kills Tybaly after Tybalt killed Mercutio. Benevolio, Mercutio and Romeo meet Tybalt and Tybalt tries to provoke the Montagues. Romeo refuses to fight, but Mercutio fights instead. Tybalt kills Mercutio, so Romeo then kills Tybalt.
In Act III, Scene 1, Mercutio was the first one to mention fighting. Eventually, Tybalt stabs Mercutio.
Mercutio is quite happy to fight Tybalt, who he dislikes intensely. Romeo is trying to avoid fighting Tybalt because he is Romeo's wife's cousin (although Tybalt does not know this and in fact never knows it). Mercutio has no such family ties.
He wants to stop the fight because he knows he must not hurt Tybalt because he is now related to him, and Mercutio is his friend.
Romeo kills Tybalt in Act III, after Tybalt has killed Mercutio in a duel.
