GEN1118 When you reprove someone who has wronged you, have his good in mind.   …. The Chofetz Chayim points out that the Torah does not state that Avraham reproved Avimelech for stealing his (Avraham’s) wells.   Rather, Avraham admonished Avimelech for not having prevented his servants from behaving dishonestly.   It was the wrong that bothered Avraham – that the servants were not restrained – and not his person loss.   HaChofetz Chayim, vol 3.   When you admonish someone for having wronged you, do not allow personal anger to taint the reproach.   Your goal should be to correct the other person’s behavior and not to “get even” with him.  PLYN 84-5
