4. Etymology: "Perpetrator" is from 1570, from Late Latin perpetrator, from Latin perpetrare; a derivative of the verb patrare, which originally literally meant, "to perform or to accomplish in the capacity of a father"; an act that might be "good or bad"; however, in English, the verb was first used in the law (statutes) referring to crime; hence, the negative association has been the dominant meaning ever since.
