The only difference being that Lucrezia doesn't think it's wrong at all, to live as if the whole world stands against her family. It's kill or be killed, put crudely. Though she prefers to use rather than be used, which she thinks is already kindness compared to what her father, her brothers, would demand.

At this moment, Cassandra is useful to her. She is kindness personified and she is stronger than most which, Lucrezia has learned, is an essential trait for any who wishes to come close enough to her. She has lost too many. She would rather gain fewer friends than lose too many more. It's true that she's afraid for her own safety, and that little trip to Florence didn't help any, but she also fears for the lives of those who come too close. She holds on tighter too and takes a deep breath to clear away the weight in her chest, heavy like sorrow or perhaps like joy. It's hard to tell.

"I know now. You can tell for yourself, can you not?"
