Consciencestricken is a term used to describe a person who is experiencing guilt or remorse. Some antonyms for this word could be unrepentant, remorseless or apathetic. An unrepentant person does not feel any guilt or remorse for their actions and refuses to admit their wrongdoing. A remorseless person is also someone who is without feeling or regret for their actions. An apathetic person, on the other hand, may not feel guilty or remorseful because they simply do not care about the consequences of their actions. These antonyms highlight the opposite of a consciencestricken person, who acknowledges their wrongdoing and feels genuinely contrite.
