Bhagavad Gita Chapter 1, Verse 37

यद्यप्येते न पश्यन्ति लोभोपहतचेतसः | कुलक्षयकृतं दोषं मित्रद्रोहे च पातकम् ||

yadyapy ete na paśyanti lobhopahata-cetasaḥ kula-kṣaya-kṛtaṁ doṣaṁ mitra-drohe ca pātakam

Though these, their hearts overcome by greed, see no guilt in destroying their family, no sin in treachery to friends.

Arjuna diagnoses the enemy: 'lobhopahata-cetasaḥ'—minds overcome by greed. Their inability to see isn't ignorance—it's selective blindness. They 'na paśyanti' (don't see) the fault in family destruction or betraying friends. Why? 'Lobha' (greed) has 'upahata' (impaired) their 'cetasaḥ' (judgment). You don't need to be evil to do bad things—you just need to want something badly enough that you stop seeing clearly. The insight: moral blindness isn't permanent character flaw, it's temporary distortion caused by desire.
