Fill him with hallucinatory drugs! Out him in a dangerous environment! talk to him through microphones. Give him love - take it away. Isolate him. Make him kill, then face him with death! For the man with no name it took the murder of Cathy, the saloon girl, to make him put on his gun and kill. This man who chucked in both his badge and gun at the beginning, then later refused to be hired, to wear the badge or gun offered to him by the Judge. But is man really his own master, the Captain of his soul? If you were in the man with no name's position, what would make you kill? Will there, and should there, still be things worth killing for in this world of ours? It would be a sad look out for the human race if ever there is not. Remember the Eloi in H.G. Wells The Time Machine.
Be seeing you
