Great Hopes was a famous novel by Dickens. Pip's sister was named Emma. In the novel, Emma was described as a strong and independent woman, but she was often abused by her sister Pip. Pip and Emma live in the same family, but their relationship is very disharmonious. Pip often bullied and abused her, sometimes even violently. This behavior may be because Pip's parents died when he was young, and he felt that he had no one to rely on, so he became more dependent and close to his sister. In addition, Emma might have received strict training from her family to become a strong and independent woman. She felt that she had to take care of herself and not let anyone hurt her, which led to a conflict between her and Pip. To sum up, the reason why Emma abused Pip was probably because she had received a strict family education from an early age to become a strong and independent woman, and her relationship with Pip was very disharmonious.
