Is there a word for a person who has been coerced into doing something because he lacked the intellectual wherewithal to evaluate it beforehand?
Context: A lot of fraudulent conversions from traditional religions into organized religions has happened in Asia and Africa, where spurious reasoning of God and Truth was provided to carry out conversion activity and people were coerced into accepting a new religion.
I don't want to use the word victim here, as victim is a very broad word. I am looking for a specific word to reflect this situation?
