Who is Man from Without Feathers and what is their importance?

An unnamed man answers Kleinman's cries for help as the doctor is dying. The same unnamed character of "Man" later demands, at knife point, that Kleinman pick a side in the growing civil war. Man represents the sometimes irrational public. While Man is reasonably amiable under normal circumstances, he is prone to blind emotionalism when placed under duress. He is, in essence, a one-man mob.
