अहो बत महत्पापं कर्तुं व्यवसिता वयम्। यद्राज्यसुखलोभेन हन्तुं स्वजनमुद्यताः॥
aho bata mahat papam kartum vyavasita vayam yad rajya-sukha-lobhena hantum svajanam udyatah
Translation
Alas! How strange it is that we are preparing to commit great sins, driven by greed for royal pleasures, and are intent on killing our own kinsmen.
Commentary
Arjuna laments the irony of the situation — they claim to be righteous yet are about to commit the worst sin. His self-reflection is genuine, but he fails to see that defending dharma is not greed.
