"How does your world handle things like this?" Superman also felt it was wrong for General Zod's body to be taken by the military. At first, he had merely felt uncomfortable that the body of one of his own kind was being desecrated, but after Stark's explanation, he too thought of all the trouble that could follow.
Once Earthlings got their hands on General Zod's body, they would definitely conduct all kinds of experiments.
They would want to uncover the secrets in Kryptonian genes and find the reason for their immense strength. Slicing, analysis, research—they would distribute Kryptonian genes among several major laboratories like pork, allocate huge funds, and gather personnel to tackle the problem. It did not take much intelligence to imagine such things.
If one day Earthlings discovered that they did not have enough samples, they would turn their attention to him and his cousin.
This was not Superman being paranoid. It was something that would definitely happen.
Unlike his foolish cousin, Superman was already thirty years old. He had seen much of humanity's darkness, but constrained by various moral considerations, he had still allowed the military to take General Zod's body.
Now, he wanted to ask Stark whether there was any advanced experience they could learn from.
Did his own side have any advanced experience worth learning from? Stark began to ponder it, but after thinking it over and over, he realized there really was not much.
Whenever anything appeared, Director Daisy would forcibly take it away with excuses like, "This is mine," "This is mine too," and "These, these, and all of these are mine."
Earth's governments and militaries had been forcibly kept outside a security boundary by S.H.I.E.L.D. They did not get involved with alien artifacts, while S.H.I.E.L.D. did not participate in their political games.
