Who is Don Luigi Magalone from Christ Stopped at Eboli and what is their importance?

"Professor" Don Luigi Magalone is the Mayor of Gagliano. In some ways, he is a villain in the book, but this would be too simple of a description. Don Luigi is overweight, with oily black hair and black, insincere and self-satisfied eyes. He was the town elementary school teacher but was charged with watching the political prisoners in Gagliano. He did this, Carlo notes, with "gusto and zeal." Don Luigi is a committed Fascist, attempting to get the townspeople to care about Fascist politics. Yet the townspeople are indifferent. Throughout the book, Don Luigi occasionally becomes an annoyance to Carlo, but usually little more than that. In actual fact, Don Luigi is terrified of his enemies and his bosses and revels in any approval he receives from a civilized man like Don Carlo.
