Which concept suggests that individuals are possessed by spirits that cause evil behavior?

Demonology is the concept that suggests individuals may be possessed by spirits or demons that influence their behavior, often leading them to commit acts that are considered evil or immoral. This idea stems from historical beliefs that more than just psychological or sociological factors influence a person's actions; rather, external supernatural forces are at play. In various cultures and religions, demonology has been used to explain behaviors that are otherwise difficult to understand through the lens of reason or criminal psychology.

Mythology involves traditional stories that may explain historical events, natural phenomena, or cultural practices but does not specifically address the concept of possession leading to evil behavior. Spiritualism is related to the belief in the communication with spirits, usually through mediums, but does not imply that spirits cause evil acts. Psychology focuses on the mental processes and behaviors of individuals, relying on scientific methods and research to understand human behavior without invoking supernatural explanations. Thus, demonology is very distinct in its emphasis on the influence of spirits on individuals' moral decisions and actions.
