How does the author emphasize the change in Nnamabia’s character over the course of the story

Namibia is a character from the book "Cell one" by Chimamanda Ngozi Adichie

Namibia was portrayed by the narrator as very beautiful in the story in Cell One of the novel. Namibia engaged in theft, got caught and was imprisoned. At the cell one where he was imprisoned, he met an innocent old man.

The man was apprehended by the police because the police could not find his son that was "wanted". Namibia behaved in kindness towards the old man. He revolted the torture and maltreatment of the Old man by the police because he was sick and innocent.

This act of kindness reflected how the Author changed the character of Namibia from a character was that was caught for engaging in social vices of stealing to being kind and showing an act of benevolence towards the old man.

because he is using a description to provide evidence to support his argument.

hope this could
