I think Jack Kirby's reaction to seeing what DC has done with the Fourth World would be like Old Testament God and the Jews. "What? No! You're not allowed to have Superman and Barda make a porno! Are you trying to split them up? Stop that! Wait, Scott has the Anti-Life Equation and accidentally used it to commit mass murder and now he has angst over that? What is wrong with you? Oh, Barda's playing Pokemon with a little girl. THANK YOU.
