The infamous "shock" experiments conducted by Stanley Milgram in the 1960s showed just how far people would go, when ordered to hurt somebody else by an authority figure. The well-known psychological study brought in volunteers who thought they were participating in an experiment where they would deliver shocks to another test subject. A doctor requested that they deliver greater and greater shocks, even when the "test subject" started to scream in pain and (in some cases) die. In reality, the experiment was to see how obedient people would be when a doctor told them to do something that was obviously horrific and possibly fatal.
