How does Victor feel about Elizabeth in Frankenstein

Caroline Frankenstein made a habit of visiting the poor: since she herself had been saved from poverty, she felt it her duty to improve the lot of those who did not share her good fortune. One day, she discovered an angelic girl-child, with fair skin and golden hair, living with a penniless Italian family. As the girl was an orphan, and her adoptive family lacked the means to care for her, the Frankensteins determined to raise the child as their own. The child, whose name was Elizabeth Lavenza, became Victor's sister and his constant companion, as well as the object of his unquestioning worship. For him, she is his most beautiful, most valuable possession.
