Eric Sacks ridiculous scheme
In my opinion Eric Sacks plan to sell a "cure" for a threat that he created is even more stupid than Luthor's real estate scheme in SUPERMAN the movie.
First if he would release a toxin via the spire of his building, all the authorities would held him responsible (because of intent or neglect), especially after he "miracilously" comes up with a cure shortly after the incident (which might work as a cure on people, but probably causes mutations).
It is far more likely that the government would hunt him down as a domestic terrorist (which he is, even though his motives are monetary gain and not political.
Creating or generating a demand for the mutagen was completely unnecessary to begin with.
We are talking about a substance that can heal any illnesses, poisoning, regenerate cells and increase strength and intelligence.
He could have made billions if he had sold the mutagen to the military (which they could use to create human supersoldiers or mutate animals and turn them into weapons, like Rocksteady and Bebob).
