Dicken's portrayal of Fagin is quite unsympathetic, emphasizing his unsavory appearance and questionable morals. He is described as having "a face, which, if it had been a mirror, would have shown a mind warped and distorted by the every bad passion," suggesting a deeply corrupted individual.
Fagin's actions reflect his sinister nature. He exploits the vulnerability of impoverished children, turning them into pickpockets and thieves to serve his own selfish interests. His callous disregard for their wellbeing is evident in his lack of concern for their physical or emotional well-being.
One particular aspect of Fagin's character that stands out is his manipulation of Oliver Twist, the protagonist of the novel. After taking Oliver in, Fagin initially presents himself as a benevolent figure, providing the young boy with shelter and food. However, it soon becomes clear that Fagin's motives are far from altruistic, as he gradually introduces Oliver into the world of crime.
Overall, Fagin's first impression in OliverTwist is that of a villainous and calculating individual who preys on the vulnerabilities of others for personal gain. His presence sets the stage for a gripping tale of good versus evil, as Oliver strives to escape the clutches of Fagin's criminal influence and forge a better path in life.
