Mordechai would not listen to their attempts to convince his to bow to Haman. This seems to imply that they attempted to help him change. However, that does not necessarily mean that they were righteous. According to the Talmud (Niddah 61a), Og also told Avram of the threat to his nephew Lot’s life (Bireishis 14:13) for his own desire to see Avram die and make his wife Sarai available for himself. Despite his evil intentions, the Midrash (Bireishis Rabbah 42:8) teaches that Og is nevertheless rewarded. These servants, too, may have had their own motivation in Mordechai’s conforming to their behavior.
