Deceit is against truth, defined as speaking falsehood with the intent to deceive, offending charity and justice, and leading others into error. While the Church condemns deliberate falsehood, it distinguishes between intentional lies and unintentional errors or figurative speech, noting that extreme circumstances might justify actions that seem deceitful for a higher good, though the act itself remains serious, with gravity determined by intent and harm.
