Castle, on the other hand, in The Human Factor, did not display such blind loyalty. Unlike Stevens, Castle doesn't consider himself as big or better than anyone else. He has nothing to prove to anyone. Initially, he was very loyal to his country, accepting a government position and even traveling around the world to Africa for his work.
