In both "Oliver Twist" and "David Copperfield," Charles Dickens poignantly explores themes of innocence and suffering, reflecting the harsh realities of Victorian society. In "Oliver Twist," innocence is embodied by the character of Oliver, a young orphan who remains inherently good despite the cruelty surrounding him. His suffering highlights the brutal conditions of the workhouse and the exploitation of the poor. Dickens uses Oliver’s plight to critique societal indifference and the systemic injustices faced by the vulnerable. Oliver's innocence serves as a moral compass, contrasting sharply with the corruption of figures like Fagin and Bill Sikes, ultimately emphasizing the resilience of the human spirit amidst suffering.

Conversely, "David Copperfield" presents a more complex journey of innocence lost and regained. David’s early life is marked by hardship and emotional turmoil, stemming from his abusive stepfather and the loss of his mother. This suffering shapes David's character, leading him through a series of trials that force him to confront the realities of adulthood. Throughout his journey, David’s inherent goodness shines through, guiding him toward self-discovery and redemption. Unlike Oliver, whose innocence is preserved, David navigates the complexities of human experience, ultimately finding hope and fulfilment.
