Yes, although Shylock is harsh on Jessica, she should feel ashamed that she is destroying her father in one fell swoop. The full answer can be seen at:
Like I said, Jessica had not had an easy time with Shylock. He locked her up and hoarded her like his other treasures. Still, he did love her. Jessica's betrayal was too harsh. She gave her father no chance to make amends or change his ways. She really destroyed him at one time.
I think Lorenzo's love was always in question. He demanded much of her that had little to nothing to do with love. He wanted her conversion, her father's wealth and the punishment of her father. His motives for "love" can truly be questioned.
