If this is how you've presented the question, Its a bit hard to answer it when one hasn't read these books. It'd be best if you'd put both books into a summary for us to go based off of, at most. 
        
             
        
        
        
Hello. You have not asked any questions related to this text, which makes it impossible for me to answer you. However, I will try to help you by showing you what this text means.
This text is an excerpt from "Romeo and Juliet" written by Shakespeare. As you may already know, "Romeo and Juliet" tells the story of forbidden love between Romeo and Juliet who are the children of enemy families and therefore cannot be together, even if they love each other.
This passage refers to the moment when Tybalt, Juliet's cousin, kills Romeo's friend Mercutio, completely unjustly and unnecessarily. Romeo, is upset by this death and decides to take revenge. It is at that moment that he declaims the words contained in that text, stating that revenge must be so complete, that he must kill Tybalt, or himself.
