Could it ever be sufficient for a perpetrator, someone who had committed some of the most dastardly and gruesome atrocities, to be allowed to get off scot-free as it were with only a confession, a full disclosure, since, as it happens, the act under which we operated did not require that the applucant should express contrition or remorse?

Archbishop Desmond Tutu
No Future Without Forgiveness, p. 49 1999

If your brother sins, rebuke him, and if he repents, forgive him; and if he sins against you seven times in the day, and turns to you seven times and says, “I repent,” you must forgive him.

Jesus
Luke 17:3-4

God forgives, but (not without) repentance.

Muhammed
The Sayings of Muhammed, 209
