What is the main effect of describing key events in the narrative as accidents or as happening by chance?

Describing key events in a narrative as accidents or occurring by chance emphasizes the role of randomness and unpredictability in the storyline. This perspective can create a sense of fate or inevitability, suggesting that characters are subject to forces beyond their control. Additionally, it may evoke themes of coincidence and the fragility of human plans, highlighting how unexpected events can significantly alter the course of the narrative. This approach also invites readers to reflect on the nature of chance and its impact on life and decisions.
