No, omnibenevolence is the concept that everything and anything that God does is irrefutably good, simply because God did it. In theory, God could kill your children and eat them and it would be an act of goodness. That is a classic example, and the scholars always add that God would never do such a thing, but IF HE DID, The tale of Job is justifiedas a decent, good and moral act by the doctrine of omnibenevolence, The Wikipedia link I sent is pretty accurate.
