Death

Death in this scene is depicted to Romeo as basically saying "if I can't be with Juliet I might as well be dead". To him Juliet is the only think keeping him alive and without her he believes there is nothing worth living for. Romeo has been sentenced to be exiled, which means banished from Verona, meaning he won't see Juliet ever again, and to him, she is his everything and without her he would rather die. In this scene, Romeo is basically saying that being exiled is just as bad as killing him because they are taking away the one thing that he is living for and his one true love, Juliet.
