When Dickens addresses the political content of his story, I think he's a bit more shifty & clever as to his loyalties than what you represent.
Regarding the French peasants, the most sympathetic is the unnamed adolescent brother of Therese DeFarge, who dies trying to defend the honor of their elder sister in the wake of her rape by the evil Marquis Evremonde. He's a minor character, and Dickens is careful to have him live and die before he could have been involved in the revolution. The high drama of the brother's death by the sword of the Marquis notwithstanding, he's relegated to a servant class similar to the positions held by Jerry Cruncher & Miss Pross. Under the rigid class system, which I believe Dickens to have been loyal to, its okay for a bright individual to be full sassy independence, so long as he/she clearly confines himself/herself to the inferior position in all matters of importance.
Also, in the wake of the account of the avenging brother, which gives the appearance of strong narrative sympathy for the sufferings of the peasants, Dickens strategically swings the POV back toward antipathy for the peasant revolution by having peasant leader Ernest DeFarge use an outdated denounciation of Darnay by his father-in-law, Dr. Manette, a folk-hero of the revolution. According to Dickens' view of things, the French peasants are, for the most part, either brute savages or cold-hearted strategists.
The ruination of the character of Therese DeFarge by blind hatred overshadows all of the sympathetic portraits of the peasant revolutionaries.
In contrast to Madame Therese, we have Sydney Carton, the profligate English lawyer who sacrifices & redeems himself on behalf of the aristocratic Evremonde family.
