(Book 2 Chapters 1-6) What attitude does Carton have toward Darnay, judging from what he says to himself in the mirror (the glass hanging on the wall)?

After Darnay leaves, Mr. Carton looks at himself in a mirror and reflects that he does not like Darnay because he too much resembles what Carton himself could have been, had Carton not been so dissolute. He hates Darnay for inspiring Miss Manette to look at him with such compassion.
