Count Zaroff is a character in the 1932 classic film The Most Dangerous Game. Many consider this character to be cunning do to his manipulation of fellow protagonist Bob Rainsford.
... The Zaroff from Doctor Who is a Professor, and does not hold any military rank. However, I suspect you are talking about General Zaroff from "The Most Dangerous Game" (also known as "The Hounds Of Zaroff"), which is a short story and completely unrelated to Doctor Who. Perhaps you put this question in the wrong category?
