“ Though she had been surprised to find that murder was so thoroughly enjoyable, Mrs Bennet did not believe that this reflected any fault or wickedness in her character. She knew she only committed these acts tosecure the future well-being of her daughters. Naturally, she would be able to stop killing once her daughters had husbands and there was no further use for such bloodthirsty deeds. Indeed, she felt adamant that she only enjoyed the planning and execution of such matters because her daughters had not been so good as to provide her with wedding preparations to occupy her active mind. ”
