A karen is someone who gets in other peoples business. Makes people do what they want. If no one does what the karen wants, yhe karen will spend all their energy to make it happen. Usually by calling the manager, a person in charge. In this case wouldn't the karen be the person trying to make other people wear the mask, and would cry and scream to the manager (in this case the government) to make people wear mask. People not wearing mask are not in other peoples business, they wouldnt be the karen. I would say monkey puppet wouldnt be the karen. I get the point but karen would not be the word for what you are implying.
