what are all the ways (directly and indirectly) that the author lets us know the grandmother is not an admirable person?

In A Good Man is Hard to Find, O'Connor reveals the grandmother’s lack of admirable qualities in both direct and indirect ways:

Self-Righteousness: She constantly criticizes others, believing she is morally superior, like when she judges the family's lack of manners or calls people "bad" for not being "proper."
Manipulation: She manipulates Bailey into taking a detour to see a house from her past, even though it's out of the way and makes him frustrated.
Racial Prejudices: The grandmother makes derogatory comments, such as referring to people as "poor white trash" and making other racially insensitive remarks.
Vanity and Self-Image: She dresses up in an elegant outfit for the trip, thinking it will make her appear like a lady in case of an accident, showing her concern with outward appearance over practicality.
Lack of Compassion: Although she presents herself as a "lady" and a "good person," her actions lack true kindness or empathy, and she often judges others harshly without offering help or understanding.
Hypocrisy: She talks about being a "good person" and having Southern values, but her actions don't align with those beliefs. She often fails to act according to the principles she claims to hold.
Moment of Grace: In her final moments, when facing death, she has a brief moment of spiritual realization, calling The Misfit "one of her own children," but it comes too late to change her fate.

These aspects show that the grandmother, despite thinking of herself as a "lady" or morally superior, is deeply flawed, self-centered, and disconnected from the ideals she claims to uphold.

At the end of A Good Man is Hard to Find, the grandmother experiences a brief moment of grace, realizing her own moral flaws and seeing the Misfit as a fellow human being, which reflects a sudden, though fleeting, understanding of compassion and shared humanity. Unfortunately, this realization comes too late to save her, as she is immediately killed. The Misfit, in contrast, remains unchanged. His killing views on life and punishment persist, and he expresses that the only joy he finds is in meanness, remaining emotionally unaffected by the grandmother’s gesture. Thus, while the grandmother has a moment of clarity, the Misfit remains steadfast in his lack of empathy or redemption.

what, if anything, do the grandmother and the misfit learn by the end of the story?

By the end of A Good Man is Hard to Find, the grandmother and The Misfit experience different realizations. The grandmother has a brief moment of clarity, recognizing The Misfit as "one of my own children" and perhaps feeling a sense of compassion, but it comes too late to redeem her, as she is immediately killed. The Misfit, however, remains unchanged, reflecting on his nihilistic worldview and the meaningless of life, despite the grandmother's appeal. He is unmoved by her moment of grace, and his philosophy of life, devoid of redemption, remains intact. Ultimately, the grandmother's brief insight contrasts with the Misfit's continued moral emptiness.
