compunction: [14] Etymologically, to do something ‘without compunction’ means literally to do it without one’s conscience pricking. The word comes via Old French componction from late Latin compunctiō, a derivative of compungere ‘prick hard’, a compound verb formed from the intensive prefix com- and pungere ‘prick’ (source of English puncture and pungent).
