What term describes a deviation or aberration from a moral standard or normal state?

The term that describes a deviation or aberration from a moral standard or normal state is "aberration." In various contexts, especially in ethics and morality, "aberration" refers to actions or behaviors that diverge from what is considered acceptable or typical. This deviation can indicate a temporary lapse or an unusual occurrence that stands out in contrast to expected norms or standards.

The other terms do not accurately fit the definition provided in the question. "Absolve" means to free someone from guilt or blame, which does not relate to a deviation from a standard. "Abjure" refers to formally renouncing or rejecting a belief or cause, whereas "abrogate" means to abolish or annul, typically in the context of laws or agreements. These terms focus on different concepts and do not align with the idea of deviation or aberration from a moral standard.
