What would be a good topic or central issue to choose for an essay about Philip Roth's novel Nemesis?
Philip Roth's novel Nemesis touches on many different important themes, including religion, love, guilt, duty, and disability.

There are several religious aspects of the novel you could discuss. One possibility would be the relationships between the Italian (Roman Catholic) and Jewish characters. How are these relationships informed by wider world events?

How is that echoed in the novel?
Another possible approach would be a study of the disease polio and how it affected the characters in the story. In a sense, polio functions within the story almost as a character, terrifying and unpredictable. Before the Salk vaccine, people lived in terror of this disease. How does not only polio but the fear of polio affect the characters of the story?
