Bhagavad Gita: Chapter 1, Verse 38-39

यद्यप्येते न पश्यन्ति लोभोपहतचेतसः ।
कुलक्षयकृतं दोषं मित्रद्रोहे च पातकम् ॥ १-३८ ॥

yady apy ete na paśyanti lobhopahata-cetasaḥ
kula-kṣaya-kṛtaṁ doṣaṁ mitra-drohe ca pātakam 1.38

Although their thoughts are overtaken by greed, see no wrong in annihilating their family or quarreling with friends

कथं न ज्ञेयमस्माभिः पापादस्मन्निवर्तितुम् ।
कुलक्षयकृतं दोषं प्रपश्यद्भ‍िर्जनार्दन ॥ १-३९ ॥

kathaṁ na jñeyam asmābhiḥ pāpād asmān nivartitum
kula-kṣaya-kṛtaṁ doṣaṁ prapaśyadbhir janārdana 1.39

Yet, O Janardana, why should we, who can see the crime in destroying a family, engage in these acts of sin?
