Thus the criminal ceases to be a person, a subject of rights and duties, and becomes merely an object on which society can work. And this is, in principle, how Hitler treated the Jews. They were objects; killed not for ill desert but because, on his theories, they were a disease in society. If society can mend, remake, and unmake men at its pleasure, its pleasure may, of course, be humane or homicidal. The difference is important. But, either way, rulers have become owners.
