Final answer:
In medieval times, abnormal behaviors were seen as a sign that a person was possessed by demons, which was in line with the religious and superstitious beliefs of that period.
Step-by-step explanation:
In medieval times, abnormal behaviors were viewed as a sign that a person was possessed by demons. This perspective was informed by the prevailing religious and superstitious beliefs of the era. Events from illness to natural disasters were often interpreted as spiritual or demonic in nature, and abnormal behaviors were no exception. The popular view was that such behaviors were a manifestation of demonic possession, and the person in question needed to be exorcised or subjected to other religious rites to be cured.
Abnormal behaviors were a cause for alarm and were often met with fear and suspicion. This was a time when the lines between the natural and supernatural were blurred, and the explanation for most unexplained phenomena tended to lean toward the presence of malevolent spirits or divine retribution. As a result, those exhibiting such behaviors were often treated with a mix of fear, pity, and a strong drive to 'cure' them through religious means.
