Throughout the play Tybalt was constantly angry with the Montagues especially with Romeo. His anger is fueled when he discovers that Romeo crashed the Capulets party, after that night he wants to kill Romeo. However he does not succeed, instead of killing Romeo he fatally stabs Mercutio.That one mistake causes him his life, “romeo slew him.” In the play William Shakespeare never explains why the Montagues and Capulets are fighting or why there is a big feud. Tybalt is only part of the feud because he thinks he has to, he is fighting a fight that is not his. It is their parents. The feud is pointless if the two respected do not know why they are fight. The lack of communication within and out of his family is the reason for Tybalt's anger
