You get the right mad scientist to agree with your worldview and you can do it. Mengle, Unit 100, Unit 731... Real life Dr. Frankensteins. They’d do it for free if it aligns with their weird science goals and 600k could probably buy some nice lab equipment. Look at Mike Adams from natural news. He has a certified lab that can do scientific research. He’s also pretty well off, though.

You must understand That to elevate to a position of power in communist countries you have to swear your mind body and soul to the allegiance in mission of the communist party. “Money” is a nasty thing to “desire.” Communism mostly replaced Buddhism in China. Total obedience to the party and state... because you are not an individual, but an extension of the state.

You could also find a recent doctorate in the relevant field, offer to pay off their student loan debt of $200,000 and still have $466,000 to outfit their lab if they just juice a natural virus/parasite like was done with anthrax. They say “but that’s evil!” Give them the schtick about “nooo this is potential lifesaving research that can help us find cures.” Chemical weapons? Ricin i believe, was the poison of the tokyo doomsday cult, and it’s made from the seeds that make castor oil. Cyanide is in apple seeds. Anti-biotic resistant syphilis is becoming a thing... where there’s a will there’s a way...

Please don’t develop a bioweapon, though, there’s already so many out there.
