This perspective highlights the idea that societal influences and personal experiences play crucial roles in shaping behavior.

Mankell also emphasizes that crimes serve as a lens through which the complexities and contradictions of human life can be examined. His writings delve into these themes, suggesting that exploring criminal acts reveals deeper insights into morality, society, and the human condition.
