This really depends on your own opinion. Personally I believe that they shouldn't feel very guilty as they were only helping Romeo and Juliet with the choices they made. The Nurse even stopped supporting Juliet after Romeo was banished and suggested she should marry Paris, although this did mean Juliet was left alone. Friar Lawrence advised both of them before he married them that it was moving along to fast and he shouldn't feel guilty about Juliet's death since he did arrive in time to save her and he did try to convince her to leave the tomb with him and even if he didn't try very hard, Juliet still made the decision to end her own life.
