Answer:
The story is told from multiple perspectives, each of which provides its own account of what happened. It is up to the reader to interpret the various accounts and determine which, if any, are more reliable or trustworthy than others.
It is also possible that each character is telling the truth as they understand it, but their perspectives and biases may affect their recollections of the events. Additionally, the story's structure, with its shifting perspectives and incomplete information, intentionally leaves the truth ambiguous and open to interpretation.
Ultimately, the question of which character is more trustworthy may be less important than the larger themes of the story, such as the nature of truth, the limits of human perception and understanding, and the complex interplay of power and morality.
