Understanding 'Audacity' in Context

In literature, the term protagonist refers to the main character in a story, often facing conflict or adversities that catalyze their growth. While they are typically viewed positively, narrators can complicate this perception through the inclusion of flawed characteristics or morally ambiguous decisions. The protagonist's journey often involves pivotal moments of insight where they reflect on their choices, leading to a transformation.

Consider the following excerpt from a novel:

'Though her intentions were noble, the protagonist often acted with a certain level of audacity, which led to unexpected consequences. Her audacity, in many situations, proved to be both a strength and a liability as she navigated her relationships with others.'
