Why do you think Sydney Carton resents Charles Darney? Does this seem like a realistic response to their personal situation?What happens to Sydney Carton and Charles Darney???
In "A Tale of Two Cities" Carton is considered Darnay's double and alter-ego as they both are somewhat frustrated in their social situations, for one thing. Darnay has been forced to come to England to take refuge as an Evremonde, while Carton is a frustrated alcoholic who takes refuge in drink from his disappointment in himself for allowing Stryver to use his talents. Both have a tender and adoring love for Lucie, but, of course Carton's seems more adolescent in the nature of his love as he continues to care for Lucie even after she is married.
In this adolescent nature to Carton's love for Lucie there does seems to be a lack of verisimitude. For normally a maturer man would forget about Lucy after she marries, but in the fiction of Dickens, his characters often have very intense sentimental attachments. Sometimes Carton looks at Darnay and, noting the resemblance between them, seems to wonder what it is that he has lost to make him the inferior of Darnay. In Chapter 6 of Book the Second when he hears the footsteps coming "fast, fierce, and furious, Carton feels a sense of impending doom, and then, too, he may envy Darnay for the love he has with Lucie as he is so alone.
While Darnay is society's innocent victim as the son of the man who is responsible for the death of Mme DeFarge's brother, Sydney carton is the sacrificial hero who takes Darnay's place and redeems the sins of the Evremonde in the imitation of Christ.
