Judaism mandates forgiveness, if it is asked for.
"It is forbidden to be obdurate and not allow yourself to be appeased. On the contrary, one should be easily pacified and find it difficult to become angry. When asked by an offender for forgiveness, one should forgive with a sincere mind and a willing spirit. . . forgiveness is natural to the seed of Israel." (Mishneh Torah, Teshuvah 2:10)
