What type of monster in German Expressionism is characterized by a disfigured human being seen as evil?

The correct answer is rooted in the themes and representations often seen in German Expressionism, which frequently depicts characters as manifestations of inner psychological conflicts. The term "Old Testament monster" refers to the portrayal of beings that symbolize moral ambiguity, punishment, and the struggle between good and evil, often reflecting societal fears and anxieties.

In German Expressionist films, characters that are disfigured or monstrous are often associated with supernatural elements or radical social commentary. These figures can represent the darker aspects of humanity and serve as cautionary symbols of what happens when societal norms are broken or individualism becomes twisted. They embody societal paranoia and fears, and their disfigurement or monstrous qualities emphasize their 'evil' nature.

The nature of these characters aligns with themes visible in works like "The Cabinet of Dr. Caligari," where the disfigured and psychologically disturbed challenge the notion of morality and the human condition. In contrast, the other categories—such as Darwinian, Freudian, or Natural monsters—reflect different theories of monstrosity and humanity that do not specifically emphasize the disfigured aspect related to deep-seated evil as depicted in German Expressionist cinema.
