Bhagavad Gita · 1.38

कथं न ज्ञेयमस्माभिः पापादस्मान्निवर्तितुम्।कुलक्षयकृतं दोषं प्रपश्यद्भिर्जनार्दन॥

kathaṁ na jñeyam asmābhiḥ pāpād asmān nivartitum kula-kṣhaya-kṛtaṁ doṣhaṁ prapaśhyadbhir janārdana

Why should we, who can clearly see the crime in destroying families, not turn away from this sin, O Janardana?
