SB 1.7 - Two pure devotees disagree how best justice can be done

Yudhiṣṭhira fully supported the statements of Draupadī, which were in accordance with the principles of religion and were justified, full of mercy, equality, generous and glorious. Her words were faithful to dharma because the brāhmaṇa is always the guru (SB 1.7.43). Draupadī’s plea that Aśvatthāmā be released was justified and filled with correctness because Arjuna was indebted to Droṇa, having learnt military science from him (SB 1.7.44). It was full of mercy because she did not want Kṛpī to suffer like her (SB 1.7.45). Her words expressed unwillingness to cause pain to others when she said one should not cause suffering to the family of their guru (SB 1.7.46). The feeling of equality and sense of calmness was there because Draupadī spoke out of her personal experience, being a mother herself (SB 1.7.47). Her harsh words expressed generosity desiring to benefit the hearer when she said that the angry brāhmaṇas would destroy the kṣatriyas (SB 1.7.48). And it was glorious because she wanted to show proper respect to a great family. Nakula, Sahadeva, Sātyaki, Arjuna, Kṛṣṇa, and the ladies and all others agreed with the king.

Bhīma, however, disagreed with them and recommended killing Aśvatthāmā, who had killed sleeping children. Kṛṣṇa, after hearing the words of Bhīma, Draupadī and others saw the face of Arjuna. Kṛṣṇa is referred here as Caturbhuja because Bhīma and Draupadī held opposite views. Bhīma wanted to kill Aśvatthāmā while Draupadī obstructed him. In order to prevent both of them, the Lord discovered another two arms and thus became Caturbhuja. If need be, He can display hundreds of arms.
