Syn.
– Compunction, Remorse, Contrition. Remorse is anguish of soul
under a sense of guilt or consciousness of having offened God or
brought evil upon one's self or others. Compunction is the pain
occasioned by a wounded and awakened conscience. Neither of them
implies true contrition, which denotes self-condemnation,
humiliation, and repentance. We speak of the gnawings of remorse; of
compunction for a specific act of transgression; of deep contrition
in view of our past lives. See Regret.
