If Dickens had portrayed Carton as a demonstrably good man with a clear life plan, there would have been no character development and a very important aspect of the book would have disappeared. Because Carton started out that way, it was more important when we found out that he had feelings for Lucie and the fact that he was going to save Darnay became more significant and unexpected. If Sydney had clearly been a good character, maybe she wouldn't have even saved Darnay because the opportunity may not have come because everything would have changed drastically with Sydney being different. In saving Darnay "...the former 'jackal' glimpses a better world rising from the ashes of the revolution and a long life for Lucie and her family, made possible by his sacrifice." (Morrice) Sydney is able to achieve his goal of making his name important and having people associate him with good things through his sacrifice. It makes so many things possible for the Darnays and says he gets to see "that child... making his way down that life path that was once mine." (390) The fact that Sydney is a morally ambiguous character makes him a more realistic character and people can sympathize with him more, making his sacrifice have an even greater impact. Although Sydney Carton began A Tale of Two Cities as a morally ambiguous character, by the end of the novel it was made clear that Sydney was in fact purely good. Carton's ambiguity played a very important role
