John Cothran

What do you think of John Cothran, the four-times-married manager at the Home Depot? Are there any clues in the book as to why he has such a problem with anger (we first see him destroying his car with a tire iron)? Is he going to lose his job (he seems to be losing his authority at the end of the chapter about him)? Is he racist (an all-white neighborhood was “a selling point” when he bought his house)? Sexist (one of his employees said so)? Is he any better than his grandfather, the man with his back turned? (His grandfather, John Ed Cothran, was hard to read until he said his county was the best because they didn’t even indict lynchers.)
