“Forgiveness to the injured does belong; But they ne’er pardon, who have done the wrong.”
Zulema cynically suggests that pardon belongs to the person who was harmed while the wrongdoer may remain trapped in shame or hostility; the drama immediately undercuts him by showing that he plans fresh deception.

The Conquest of Granada, Part II, Act I, Scene II (‘The Alhambra’), in The Works of John Dryden, Volume IV, Project Gutenberg #15349. Zulema says ‘Forgiveness to the injured does belong’ immediately after recalling that he has been pardoned, then declares that ‘feigned honesty’ will conceal his lust and work him back into trust. The couplet is therefore compromised fictional dramatic speech, not Dryden's neutral moral instruction or a universal rule about forgiveness.
