A person or thing that causes intense suffering, worry, or pain to themselves or others.
From 'agonize' plus the agent noun suffix '-er,' creating a word for something that inflicts agony. The Greek root 'agon' (struggle) combines with the agency suffix to name the causer of struggle.
While 'tormentor' feels like a villain, 'agonizer' often refers to someone wrestling with their own internal pain—it's a word that suggests self-inflicted suffering, which is why it's often used for obsessive worriers or guilt-ridden people.
