Tybalt was a character in the play "Romeo and Juliet." The play was written by William Shakespeare. With Tybalt's death it turned the play into a tragedy, so his death was always a certain thing. However, it could be avoided if both Benvolio and Mercutio had tried to calm Tybalt down in the story. They didn't and this led to his untimely death. Hope I helped! :) Cheers!
