Which character suggests that personal experiences shape one's perception of morality?

The character that most prominently suggests that personal experiences shape one's perception of morality is Padre Balzone. As a priest who is deeply involved in the complexities of human emotion and morality, Padre Balzone's perspective is that traditional doctrines may not fully encapsulate the nuances of individual lives. He recognizes that morality is often subjective and influenced by personal experiences, which reflects his understanding of the human condition. This idea is a recurring theme in the novel, where characters often face moral dilemmas influenced by their backgrounds and life events.

The other characters present different aspects and themes but do not explicitly express the connection between personal experiences and morality in the same way. Liesl has her own unique perspective on life but does not delve into morality in relation to personal experience. Dunny, or Duty, grapples with moral complexity influenced by his own experiences and relationships, but his character development centers more on the impact of those experiences rather than explicitly stating that they shape perception of morality. David tends to represent a more traditional view, often caught between societal expectations and personal ethics, rather than exploring the theme of morality from the lens of personal experience.
