He didn't. Romeo killed Tybalt.
Romeo was at the point married to Juliet, which is Tybalts cousin. therefore romeo did not want to kill Tybalt for Juliet's sake.
Romeo kills Juliet's cousin, Tybalt, in a fit of rage after Tybalt kills Romeo's friend, Mercutio. The act of revenge leads to a tragic turn of events in the play "Romeo and Juliet."
Romeo picks a fight with Tybalt in Shakespeare's play "Romeo and Juliet" after Tybalt insults him and his friends at a party. Tybalt challenges Romeo to a duel, but Romeo refuses to fight. This leads to Mercutio, Romeo's friend, stepping in and fighting Tybalt instead, resulting in tragic consequences.
Romeo and Juliet both kill themselves. Romeo kills Pairs and Tybalt. Tybalt kills Mecuario
i think that he killed him on the street by the water fountain.
Tybalt Killed Mercutio and then Romeo was so cross he decided to kill Tybalt! =) x
His wife, at the end of Act II.
Romeo goes on a bit of a killing spree in Romeo and Juliet. He first kills Juliet's cousin Tybalt in a duel and a few days later he kills Paris, the man that Juliet's parents want her to marry. Lastly, he kills himself by taking poison which persuades Juliet to kill herself.
There are six characters that die 1. Mercutio (killed by Tybalt) 2. Tybalt (killed by Romeo) 3. Lady Montague (died of grief after Romeo was exiled) 4. Paris (I forget how he died) 5. Romeo (commited suicide 6. Juliet (commited suicide)
It incites Romeo into killing Tybalt. The death of Tybalt not only get Romeo banished but makes it very unlikely that Lady Capulet will ever accept his marriage to Juliet. She would certainly have Romeo killed if she knew (she is planning to kill him anyway).
Romeo kills Tybalt (Juliets cousin, a Capulet) to revenge Mercutio's death, as Tybalt stabbed him. Mercutio was a Montague and jumped in the way of Tybalts sword to defend Romeo, who wanted peace from Tybalt as he had already secretly married Juliet. Romeo is then banished by the prince and the rest of the play goes on. Basically, Romeo kills Tybalt for revenge.
Romeo had to kill someone, in order for the sequence of events to happen properly. Tybalt has been set up as a quarrelsome man who imagines that he has a grudge against Romeo for crashing Capulet's party (Capulet didn't seem to mind) and so will inevitably create a fight, which creates the occasion for Romeo to kill him.
