God created Satan, and his nature, and being omniscient knew exactly what Satan was going to do, when he was going to do it, and yet, he did nothing.Because God is not a good person. At least, not in a narrative sense.

God did this precisely because he is omniscient. He doesn't just have logical scientific knowledge, he knows the secrets to life's mysteries. . . everything. He knows the future, the beginning, and the middle. . . he knows everything, the end from the beginning. He knows anything from a quadrillion years in the future. He is doing things the best way because they are the best ways. 

For example, let's say there's a little boy. He was born with damaged feet, and the Doctor's tell the father he will never walk. The father however, has found a way to surgically make him walk. Say that this is in a day before anesthesia? That's going to be one hell of a surgery for the poor little tyke. In the mean time however, there will be pain and anguish. 

Then, the little boy can walk.
