Oliver, Nancy and Miss Ross are all representatives of kindness. They were all born in misery and grew up in a world of darkness and sin. However, they always keep a pure world and a kind heart in their hearts. All kinds of hardships can't make them degenerate or completely degenerate, but they show their dazzling qualities. In the end, evil prevailed over evil. Although Nancy was finally killed, it was her death that summoned the earth-shattering power of social justice, and it was her spirit in heaven that doomed the representative of evil forces-Fagin Gang. Therefore, in the novel, Nancy's spirit is sublimated, and Oliver is rewarded in a typical sense. And the representatives of the wicked-Fagin, monks, Bambur, Sikes all came to a tragic end.
Dickens described the miserable life of poor children in capitalist society, exposed the darkness of workhouse and school education, and mercilessly exposed and lashed the darkness and hypocrisy of capitalist society.
