Passing sentence on someone means to pronounce or declare a judgment, punishment or condemnation. The very antonym of 'pass sentence on' would be to forgive, pardon, or acquit. Instead of punishing or condemning someone for their actions, the opposite would be to show mercy, understanding, or leniency. Alternatives could include to absolve, exonerate or let someone off the hook. By choosing to forgive rather than pass sentence on someone, we show compassion and empathy towards others, and allow for healing and growth to take place. These antonyms offer a positive alternative to a negative situation and promote a culture of forgiveness and peace.
