He expressed no regret for what he had done which satisfied her; his style was not penitent, but haughty. It was all pride and insolence.
– Jane Austen
Pride and Prejudice, Chapter 36. Darcy’s lack of remorse for what he had done to Jane makes Elizabeth angry. She doesn’t believe his explanation for persuading Bingley to ends things with her sister. Elizabeth, who is protective of Jane, puts it all down to Darcy’s insolent pride. The fuller quote: "His belief of her sister’s insensibility she instantly resolved to be false; and his account of the real, the worst objections to the match, made her too angry to have any wish of doing him justice. He expressed no regret for what he had done which satisfied her; his style was not penitent, but haughty. It was all pride and insolence."
