>>105738362We don't know if Weisman's Darkseid has any leads on the Equation, but I think Darkseid kept Savage around just to see what would happen to the Earth when the meta-gene spread to all of his descendants. He's been around as long as Savage, if not longer, so a decade of screw-ups are little more than a bump in the road, especially considering he left the Earth in the hands of a spear wielding primitive.
Worst case scenario, he could flatten the Earth and hand all the meta-humans over to Desaad to integrate into his legions. He seems comfortable enough using them against the League, not to mention handing them over to his least favorite son.
