question:  Why does Hendricks help Joe?
context: I've been a garbage man, street-cleaner, ditch-digger—" On the other side of the room, the jukebox came to life with a roar and a group of teen-agers scrambled to the dance floor. A civilization weary of murder, robbery, kidnapping, counterfeiting, blackmail, rape, arson, and drunkenness had originated the CPA—Crime Prevention Association. There were no longer any prisons—CPA officials had declared loudly and emphatically that their job was to prevent crime, not punish it. Instead, he was sent to a hospital where all criminal tendencies were removed from his mind by psychologists, shock treatments, encephalographic devices, a form of prefrontal lobotomy and a dozen other methods. The CPA system was, actually, cheaper than previous methods because it did away with the damage caused by countless crimes; did away with prisons and their guards, large police forces, squad cars and weapons. He was a hero to the millions of men and women who had suppressed impulses to kill someone, beat their mates, get drunk, or kick a dog. A crime because it theoretically inflicted psychological injury upon the intended victim—and because millions of women voters had voted it a crime. On the other hand, attempted murder, robbery, kidnapping, etc., were not crimes. They weren't crimes because the DCT didn't complete the act, and if he didn't complete the act, that meant simply that the CPA had once again functioned properly. Anyone who knew Hendricks well liked him, for he was a friendly, likable person. The President of the United States was a capable man, but also a very handsome one, and the fact that a man who looked something like a bulldog had been elected as New York's police commissioner was a credit to Hendricks and millions of women voters. Hendricks rose from behind the desk, walked leisurely to where Joe was slouched in a chair.
