9a. Rome is treating Jules as a godess. He is sacrificing everything, his reputation and his family, just to be with her. Like in lines 3 and 4, he's adoring her and wishing to be with her for eternity.
9b. He's described as unworthy and sinful because of how he's getting to Jules. He's hiding in secret to get to her, meaning he's lying to his family about where and what he's duing. His family is totally against the idea of him going after someone who is a rival to them. When Jules is not fighting so much in Act II. She just waits, she doesn't do actions to be with him so much.
9c. Jules is described as a saint. Meaning that her "record" is clean. So, everyone thinks that she is an angel and that she would never "comit such sin" to go and have forbbiden love.
