piacular means requiring atonement or reparation: wicked, sinful, bad.
Why “piacular” is a great word
Relating to or requiring atonement, either as being sinful and requiring expiation or as serving to make amends. From the Latin piacularis ('expiatory, atoning'), from piaculum ('expiation, atonement, sin'), from piare ('to appease, to expiate'); first recorded in English in the early 17th century. Unlike 'expiatory,' which specifies an offering meant to reconcile, or 'penitential,' which dwells in the subjective realm of remorse, piacular spans the entire grim continuum—from the stain of the offense itself to the ritual that seeks to wash it clean. It is the specific gravity of a secret guilt, the animal led trembling to the altar, and the silent, heavy air in a room where a wrong has just been named but not yet answered—acknowledging that some ruptures demand not just regret but reparation, a weight measured in acts rather than tears.
