Throughout the novel, Dickens confronts the question of whether the terrible environments he depicts have the power to “blacken [the soul] and change its hue for ever.” By examining the fates of most of the characters, we can assume that his answer is that they do not. Certainly, characters like Sikes and Fagin seem to have sustained permanent damage to their moral sensibilities. Yet even Sikes has a conscience, which manifests itself in the apparition of Nancy’s eyes that haunts him after he murders her. Charley Bates maintains enough of a sense of decency to try to capture Sikes. Of course, Oliver is above any corruption, though the novel removes him from unhealthy environments relatively early in his life. Most telling of all is Nancy, who, though she considers herself “lost almost beyond redemption,” ends up making the ultimate sacrifice for a child she hardly knows. In contrast, Monks, perhaps the novel’s most inhuman villain, was brought up amid wealth and comfort.
