Can are serial killers evil by nature be answered using scientific method?

The question of whether serial killers are evil by nature can be approached using the scientific method by examining biological, psychological, and sociocultural factors that contribute to their behavior. Researchers can formulate hypotheses about genetic predispositions, brain abnormalities, and environmental influences, then gather data through studies and case analyses. However, because concepts of "evil" are subjective and moral in nature, the scientific method can only provide insights into the underlying causes of such behavior rather than definitive moral judgments. Thus, while science can inform our understanding, it cannot fully address the philosophical implications of "evil."
