“Remorse means 'to bite again' — from Latin re- (again) and mordere (to bite). Guilt gnaws. The metaphor was literal to the Romans, who imagined conscience as an animal chewing on the guilty person's insides.”
Remordere in Latin means to bite back, to bite again, from re- (again, back) and mordere (to bite). The noun remorsus (a biting back) gave French remors and then English 'remorse' in the fourteenth century. The metaphor is vivid and specific: guilt is not a weight (that is shame) or a stain (that is sin). Guilt is a bite. It keeps biting. The re- prefix means it comes back — it bites you again and again.
Medieval Christianity formalized remorse as a necessary step in penance. The 'remorse of conscience' (remorsus conscientiae) was what you felt before confession — the biting awareness that you had sinned. Without genuine remorse, absolution was invalid. The emotion was not just morally appropriate but sacramentally required. Faking remorse was a separate sin.
Shakespeare used 'remorse' to mean both pity and guilt — the two senses coexisted in Elizabethan English. 'He was too full of the milk of human kindness to catch the nearest way' — Lady Macbeth's complaint about her husband is about his excess of remorse in the older sense of compassion. By the eighteenth century, the word had narrowed to its modern meaning: guilt felt after a harmful action, accompanied by the wish to undo it.
The legal system distinguishes between remorse and its absence. Judges and parole boards consider expressions of remorse when sentencing. Psychopathy is partly defined by the absence of remorse. The emotion has become a legal and psychiatric marker. A person without remorse is, by clinical and legal consensus, dangerous. The Latin bite that keeps returning is now a diagnostic criterion.
