Mbh 5.128.3b

Indeed, Kansa, the son of Ugrasena, abandoned by his relatives, was slain by me in a great encounter, from desire of benefiting my kinsmen. Ourselves with our kinsmen then, having paid due honours to Ugrasena, the son of Ahuka, installed that extender of Bhoja’s kingdom on the throne. And all the Yadavas and Andhakas and the Vrishnis, abandoning a single person, viz., Kansa for the sake of their whole race, have prospered and obtained happiness. O king, when the gods and Asuras were arrayed for battle and weapons were upraised for striking, the lord of all creatures, Parameshthin said thus (something which applies to the case at hand). Indeed, O Bharata, when the population of the worlds was divided into two parties and was about to be slaughtered, the divine and holy Cause of the universe, viz., the Creator, said, “The Asuras and the Daityas with the Danavas will be vanquished, and the Adityas, the Vasus, the Rudras and other dwellers of heaven will be victorious. Indeed, the gods, and Asuras, and human beings, and Gandharvas, and Snakes, and Rakshasas, will in rage slaughter one another in this battle.” Thinking so, the Lord of all creatures, Parameshthin, commanded Dharma, saying, “Binding fast, the Daityas and the Danavas, make them over to Varuna.” Thus addressed, Dharma, at the command of Parameshthin, binding the Daityas and the Danavas, made them over to Varuna. And Varuna, the Lord of the waters, having bound those Danavas, with Dharma’s noose, as also with his own, keepeth them within the depths of the ocean, always guarding them carefully. Binding in the same way Duryodhana and Karna and Sakuni, the son of Suvala, and Dussasana, make them over to the Pandavas. For the sake of a family, an individual may be sacrificed. For a village, a family may be sacrificed. For the sake of a province, a village may be sacrificed. And lastly, for the sake of one’s self, the whole earth may be sacrificed. O monarch, binding Duryodhana fast, make peace with the Pandavas.
