How does Shakespeare present the consquences of impulsive behaviour of Tybalt and Romeo in 'Romeo and Juliet'?

Throughout the play, Romeo makes very hasty decisions, some of which result in unnecessary consequences. On one occasion, Romeo goes to the Capulets Masquerade Ball where he meets Juliet and forgets about his first true love, Rosaline. Romeo spontaneously decides he was fallen in love all over again, which reflects on Romeo's impulsive character. "Did my heart love till now? For swear it, for I ne'er saw true beauty till this night."

Romeo's unwise behaviour also results in the death of Juliets cousin when his impulsive action to battle with Tybalt does not go as planned. "Either thou or I, or both, must go with him". In just one scene, Romeo's emotions overcome him and he is the cause of one death and his own banishment from Verona, "And for that offense immediately we do exile him." Romeo's sudden decisions take the lives of his friends, family and those he hates and also his own. "Romeo, there dead, was husband to that Juliet; and she, there dead, that Romeo's faithful wife." I can definetely come to the conclusion that Romeo himself is the cause of this tragic story that causes many people grief and sorrow.

Tybalt has a name that connotes energy like a bolt of thunder, an energy that is aggressive and uncontrollable. As Shakespeare portrays this to show the audience what impulsive behaviour he poses. Tybalt sets the tone for motif of violence and
