I think Oscar Schindler starts out as a self-centrered manufacturer concerned with only making money. He employs Jews not because he like them, but because they are cheap. But his perception changes and he does everything he can to save their lives. In the film, in 1943, when it became clear what the Germans' intentions towards the Jews were, Schindler ingraitated himself with the local Nazi commander, and it was only through this relationship that Schindler began his secret campaign to help the Jewish people.
