Who do you think O'Connor intended to be the protagonist of the story?

In Flannery O'Connor's "A Good Man is Hard to Find," the protagonist is often viewed as the Grandmother, as she drives the narrative and undergoes significant character development. Her journey reflects themes of grace, morality, and self-awareness, culminating in a moment of revelation. However, some readers may argue that the Misfit serves as a contrasting figure, representing the darker aspects of human nature. Ultimately, O'Connor's intention may be to challenge readers to consider the complexities of both characters and their moral implications.
