Many of Vladek's peculiar personality traits can be linked to his experiences in the Holocaust. In 1978, Vladek is stubborn, irritable, and almost comically stingy with his money. His relationship with his second wife, Mala, is strained and seemingly devoid of love. Prior to World War II, however, he exhibits none of these characteristics. He is kind, wealthy, and uncommonly resourceful, and his marriage to Anja is filled with compassion and intimacy. His experiences in the Holocaust undoubtedly played a role in these dramatic personality changes.
