Diminished responsibilities can be described using varying synonyms that all have a similar meaning. One synonym that can be used is "reduced culpability," which refers to a situation where a person is not entirely responsible for their actions due to a variety of factors. Another synonym is "mitigated liability," which means that the person may still hold some responsibility, but it is not as severe as it would be under normal circumstances. "Lessened accountability" is also an appropriate synonym that can be used to describe situations where one's responsibility is reduced due to specific circumstances. All these synonyms help to convey the idea that a person's responsibilities can be limited, depending on the situation at hand.
