Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami continued: O best of the Kuru dynasty, Kamsa was fiercely cruel and was actually a follower of the Raksasas. Therefore he could be neither pacified nor terrified by the good instructions given by Vasudeva. He did not care about the results of sinful activities, either in this life or in the next.
