In Joseph Conrad's "Under Western Eyes," the author explores the concept of evil and its origins. He argues against the notion that supernatural forces are responsible for wickedness, suggesting instead that human beings possess an intrinsic capacity for malevolence. This perspective emphasizes that individuals can engage in profound wrongdoing without any external influence, showcasing the darker side of human nature.

Conrad's assertion challenges the idea that moral failings stem from outside sources, highlighting instead the capability of individuals to commit heinous acts on their own. This reflection on human nature serves as a critical examination of personal responsibility and the potential for cruelty inherent within all people, reinforcing the theme that evil is a product of human choice rather than external, supernatural provocations.
