SB 1.7 - Draupadī's mild nature
After reaching his camp, Arjuna, along with his dear friend and charioteer, entrusted the murderer unto his lamenting wife. Arjuna is related to Kṛṣṇa as a dear friend, and the Lord acted as his charioteer. When Draupadī saw Aśvatthāmā she showed him due respects as a brāhmaṇa, even though he was condemned by Kṛṣṇa. This showed her vāma-svabhāvā, her mild and virtuous nature. Aśvatthāmā was not an ordinary person. From portions of Lord Śiva and the lord of death, and personified lust and anger – all mixed into one – he took birth.
Draupadī asked Aśvatthāmā be released, for he was a brāhmaṇa and their guru. A teacher or spiritual master is liable to be rejected if he proves himself unworthy of such a position. Aśvatthāmā failed to be a proper brāhmaṇa, and thus Kṛṣṇa and Arjuna condemned him. But for Draupadī the matter was considered not from the angle of scriptures, but as a matter of custom. A devotee of the Lord can tolerate all sorts of tribulation personally but they are never unkind to others.
