Srila Prabhupada writes, "Although Jarasandha was killed, neither Krishna nor the two Pandava brothers made a claim to the throne. Their purpose in killing Jarasandha was to stop him from creating a disturbance against the proper discharge of world peace. A demon always creates disturbances, whereas a demigod always tries to keep peace in the world. The mission of Lord Krishna is to give protection to the righteous persons and to kill the demons who disturb a peaceful situation. Therefore Lord Krishna immediately called for the son of Jarasandha, whose name was Sahadeva, and with due ritualistic ceremonies He asked him to occupy the seat of his father and reign over the kingdom peacefully. Lord Krishna is the master of the whole cosmic creation, and He wants everyone to live peacefully and execute Krishna consciousness. After installing Sahadeva on the throne, He released all the kings and princes who had been imprisoned unnecessarily by Jarasandha."
Thus end the purports of the humble servants of His Divine Grace A. C. Bhaktivedanta Swami Prabhupada to the Tenth Canto, Seventy-second Chapter, of the Srimad-Bhagavatam, entitled "The Slaying of the Demon Jarasandha."
