Romeo and Juliet are two lovers who are kept apart by their feuding families and as a result, Romeo and Juliet both commit suicide as they cannot be together. The Capulets, Juliet's family, and the Montagues, Romeos family, are the two families that are at war. Romeo and Juliet are not to blame for this but the other people in the play make the situation for the two lovers even more difficult. Capulet, the father of Juliet, may be responsible for the deaths of Romeo and Juliet because if it were not for the quarrel between the two families,...
the main one was fate. Fate controlled all of the events that took place and even at the start there are references to the deaths of Romeo and Juliet. Even though some of the characters try to go against fate, Romeo and Juliet still die as it is impossible to change fate. If something is going to happen then it is going to happen and nobody can change it. I think the only person that realized this was Friar Laurence as he says that a greater power than he contradicts has disenchanted the intentions of Romeo and Juliet.
