"Implacable resentment is a shade in a character. But you have chosen your fault well. I really cannot laugh at it. You are safe from me."

How can Elizabeth laugh at his fault when she possess the same one?

Darcy captured her dislike at the assembley. His remarks hurt her pride. I could easily forgive his pride, if he had not mortified mine. Chap 5

All Darcy's action are viewed through this dislike.

Elizabeth could not help observing, as she turned over some music books that lay on the instrument, how frequently Mr. Darcy's eyes were fixed on her. She hardly knew how to suppose that she could be an object of admiration to so great a man; and yet that he should look at her because he disliked her was still more strange. She could only imagine, however, at last, that she drew his notice because there was a something about her more wrong and reprehensible, according to his ideas of right, than in any other person present.chap 10

She has also developed a dislike to the Superior Sisters, but I think it is to a lesser degree than that for Darcy.
