Graham Greene said this quote

They killed him because he was too innocent to live. He was young and ignorant and silly and he got involved. He had no more of a notion than any of you what the whole affair's about, and you gave him money and York Harding's books on the East and said, 'Go ahead. Win the East for democracy.' He never saw anything he hadn't heard in a lecture hall, and his writers and his lecturers made a fool of him.
