Masochist
"I did nothing wrong; I was only trying to cleanse the village." The demon within tried to imitate the man's voice but failed terribly.
"And who said you did?" He mused.
Suddenly, the man was laughing so loudly, as if he found the whole event funny. The villagers who noticed the man's eyes took fearful steps away from him.
"AH! The exorcist is possessed!" Cried one of the men in astonishment. The man quickly shifted himself away from the exorcist.
When the exorcist tried to control the situation a few moments ago, a demon possessed him. There was no way he could have controlled them because they were stronger than him—he had sinned but didn't ask for mercy, and his fear ate him up.
