My foolishness results in unfortunate happenings

Oh gosh! Many tragic things have happened in this short period of time. All these actions and reactions are such a blur. There has been a death of a person very dear to me and a banishment upon myself for avenging this death. I wish I would have just left Mercutio and Tybalt fight. If I didnt get in the way of them, Mercutio wouldnt have been killed by Tybalt. My impulsitivity and bad judgement came upon me and my perspective of things. Also if I was observative and circumspect, I would have realized that the two men, Mercutio and Tybalt, were fighting out of fun, and not for the blood and death of each other. Then I clicked into another side of myself, once again, because I confronted Tybalt;I was not thinking straight and I failed to realize that killing him would be the worst decision of my life. It would result in me being banished from Verona. I had no ida that killing him would put me in an akward relationship between me and my love, Juliet. I know it is honorable to avenge my friend's death, but I should have stood up for him in another way, without a dangerous confrontation. I wish I could change myself, because I am the reason for my own banishment. I am the reason for the deaths of two men.
