God Was Not Obliged to Satisfy

Christ did not deem equality with god something to be grasped at. He humbled himself, taking the form of a slave, and being in human form, became obedient, even unto death. And paul is commending there in the second chapter of philippians, that we imitate christ. So this like parable of deep humility that's a remedy to our erroneous pride. But it's fitting, it's not necessary fitting, that god should become human and as one of us, atone for us.
