Final answer:
The quote reflects a character's internal deliberation and acceptance of an idea as a duty, a common theme in literature that highlights personal conviction and moral responsibility.
Step-by-step explanation:
The phrase 'I've been thinking over the idea until I got kind of used to it it seems a sort of duty' suggests a character's reflection on an idea or duty that has become significant to them over time. It implies a process of consideration leading to acceptance or recognition of responsibility.
This kind of statement often appears in works of literature, where characters grapple with their thoughts and emotions regarding their actions and decisions.
Examples of this can be seen in the quotes provided, where characters are deliberating over various personal and moral dilemmas, eventually finding themselves reconciled or resigned to a particular course of action that they view as their duty.
These contemplations reveal the internal conflicts and growth of the characters, underscoring themes of duty, morality, and personal conviction.
Such introspection is a common literary device that lends depth to characters and propels the narrative forward, creating engagement with the reader as they witness the evolution of the characters' mindsets.
