Because the author, Keneally, doesn’t have access to Schindler’s thoughts, the best he can do is reconstruct events based on the testimony of people who were there. When there isn’t enough information to make a clear conclusion, he lays the facts out so that the reader can decide on their own. Here, Keneally leaves it ambiguous as to whether Schindler joined a Nazi intelligence force simply to play the system, or whether he may still have had some loyalty (or at least indifference) toward the Nazi Party at the beginning of World War II.
