Pardon without repentance negates justice

Mercy is also connected with justice. [St.] Thomas Aquinas (1225-1274), a great teacher and scripture scholar, said that mercy “does not destroy justice, but is a certain kind of fulfillment of justice. ..Mercy without justice is the mother of dissolution; (and) justice without mercy is cruelty.” Pardon without repentance negates justice.
