Answer: Describing Crusoe's self-examination develops the idea of battling one's flaws.
Step-by-step explanation: In this passage, Defoe manages to reveal bits of Crusoe's history while introducing, at the same time, the character's own sense of moral development. We can infer from the words "what would become of me" that the character feels in a more advance moral place, where he can recognize having learned thankfulness and having acquired the capacity for remorse.
