So when Kṛṣṇa appeared, there were many kings. Although they were under the ruling of the Pāṇḍavas, still, Hastināpura, still they were fighting. That is natural. If one has no Kṛṣṇa consciousness, then his strength and opulence would be misused. And if one is Kṛṣṇa conscious, then he would use his strength and opulence very properly. So these kings were meant for giving protection to the citizens, to train them to the Vedic conception of life. But they were not doing that. Therefore they were demons.
