A Summary of the Srimad Bhagavatham : Ch-6. Part-15.
6: Sri Krishna’s Vrindavana and Dvarka Lilas :
In the Vrindavana Lila, Sri Krishna was a child, though he may be naughty, beautiful, enchanting, incomparably gracious, the sweetest, and the dearest of all. But in his Dvarka Lila, he became a mature gentleman of the world, and a statesman to some extent. After Krishna killed Kamsa, Kamsa’s two queens, Asti and Prapti, repaired to their father’s house in grief, and complained to him of the cause of their widowhood. Jarasandha, their father, was enraged, and attacked Mathura seventeen times, all of which were repelled by the forces of the Yadus.
But it was too much for the residents of Mathura, and Sri Krishna thought it better to leave that place. He did not want to end Jarasandha, because he had many things to do through him.

We will see to it later on.” So, Jarasandha was allowed to live, and he was not destroyed.
