Bhagavad Gita · Chapter 1: Arjuna's Despair
Bhagavad Gita 1.23
योत्स्यमानानवेक्षेऽहं य एतेऽत्र समागताः ।
धार्तराष्ट्रस्य दुर्बुद्धेर्युद्धे प्रियचिकीर्षवः ॥
yotsyamānānavekṣe'haṃ ya ete'tra samāgatāḥ | dhārtarāṣṭrasya durbuddheryuddhe priyacikīrṣavaḥ ||
I want to see those who have gathered here to fight, wishing to please the evil-minded son of Dhritarashtra in battle.
Modern context
At this point Arjuna is sure who is wrong: Duryodhana is 'evil-minded' and the rest are his helpers. Certainty about other people's faults is easy from a distance. A few verses later, having looked closely, he will not be able to speak this way.
