Step-by-step explanation:
The theme of good triumphing over evil begins to emerge at various points throughout literature, indicating a turning point where the narrative starts to shift. This thematic pivot often occurs during critical moments in the plot where the protagonists face dire situations, only to overcome them through virtue, courage, or sheer determination.
In examining the excerpts provided, these moments of thematic emergence can be identified where characters reaffirm their belief in virtue over despair, as seen in the fiend worshippers' cry that carries both despair and triumph. Additionally, the overarching narrative of a novel like Oliver Twist ends on a positive note when the protagonist is adopted by good people, signifying the conclusive victory of good over evil.
The discussion and examination of evil—whether through its gothic presentation, romantic imagination, or the inner conflict of characters—often lead to a clarifying moment where the good is acknowledged or celebrated, even if the plot involves a series of struggles and moral dilemmas. It is during such narrative arcs that the theme of good prevailing becomes pronounced.
