Tony Stark didn't just use the Infinity Stones to do a normie's patch job, that would be silly. Unfortunately, simulations didn't lead to the outcomes he was looking for, leaving him so tired and depressed on top of dying and losing his wife and daughter that he almost pulled a Wandavision, which was just terrible. He settled for dumping the problem on his therapist, namely me. That I happened to be the reformed Emperor of Space Sparta is pure coincidence.
