So for his own sake, and the safety of those around him, he lives by rigid rules he's written for himself, practicing normal life as if it were a private religion that could save him from damnation. Dead bodies are normal to John. They don't demand or expect the empathy he's unable to offer. Perhaps that's what gives him the objectivity to recognize that there's something different about the body the police have just found behind the Wash-n-Dry Laundromat - and to appreciate what that difference means.
