Why did Ingmar Bergman’s films often focus on people searching for moral standards?

Ingmar Bergman’s focus on the search for moral standards was deeply rooted in his upbringing as the son of a Lutheran pastor. This childhood environment instilled in him a preoccupation with rigorous examinations of action and motive, specifically in terms of good and bad, right and wrong.1

Even when his films were not overtly religious, his characters were often implicitly engaged in this search for moral judgment. His early fascination with the graphic, primitive religious art found in rustic Swedish churches further shaped his interest in the visual presentation of ideas, particularly the concept of evil. Throughout his career, Bergman used his work to explore human relationships and the human condition, often stripping away distractions to create abstract dramas that questioned the nature of morality and the existence of God. His films consistently reflected this intense, lifelong appraisal of the human situation, characterized by a sharp division between the worlds of good and evil.12
