Nnamabia: Good Person or Not?

In our discussion of Cell One, one of the big questions was whether Nnamabia was a good person at the beginning of the story or just at the end. I believe the answer is neither. At the beginning of the story we are given examples of how he robs the family, breaks a window in his classroom, sells exam answers to his father's students, and attempts to make his own key to the family car. I think that part of the problem here is that his mother refuses to punish him, but I believe his constant rule-breaking shows he isn't a good person at the beginning of the story. At the end, one major argument for his becoming a good person is referencing his helping the old man and refusal to dramatize his experiences in jail. The former is harder to argue against, but I believe even the worst people can have moments of humanity. As for the latter, I would say he is broken by his experiences in jail and doesn't wish to relive them.
