Bhagavad Gita 1.36 — Fear of sin
निहत्य धार्तराष्ट्रान्नः का प्रीतिः स्याज्जनार्दन। पापमेवाश्रयेदस्मान्हत्वैतानाततायिनः ॥
nihatya dhārtarāṣṭrānnaḥ kā prītiḥ syājjanārdana | pāpamevāśrayedasmānhatvaitānātatāyinaḥ ||
Meaning
What joy could we have by killing the sons of Dhritarashtra, Janardana? Only sin would come to us by killing these aggressors.
