Margaret is an educated woman who is prone to passing judgements on those around her. She spends less time in her consideration of Kevin than in her criticism of Dana. She sees that Kevin does not conform to the black role, he is not good at being in a subservient position.
With Dana, initially, she is jealous that she has managed to get the attention of both Kevin and Rufus. Because she spends much of her time alone, she focuses on criticizing others and indulging her jealous tendencies. Eventually, her feelings for Dana change after she returns to the plantation after her twins are born dead. Margaret suffers a mental breakdown, and Dana is her caregiver. They become friendly because of this time.
