Śrīmad-Bhāgavatam · Text 10.54.39
Who is speaking and story frame
बन्धुर्वधार्हदोषोऽपि न बन्धोर्वधमर्हति ।
त्याज्य: स्वेनैव दोषेण हत: किं हन्यते पुन: ॥ ३९ ॥
bandhur vadhārha-doṣo ’pi
na bandhor vadham arhati
tyājyaḥ svenaiva doṣeṇa
hataḥ kiṁ hanyate punaḥ
[Again addressing Kṛṣṇa, Balarāma said:] A relative should not be killed even if his wrongdoing warrants capital punishment. Rather, he should be thrown out of the family. Since he has already been killed by his own sin, why kill him again?
