An interesting ethical question - if papers generated in an unethical manner contain info that will help the living, should that info be published and made available? Taken to the extreme, suppose the Nazis found a cure for cancer when doing their horrendous butchering of those in death camps. Should that info be made available to the medical community, or forever condemned to obscurity because of the criminal and immoral manner in which it was obtained? No easy answers here.
Society has differing idea of Morals throughout the World. What may be perfectly acceptable in some areas, countries, may be totally unacceptable in others.
Information gained that may be very beneficial to society, regardless of how that information was obtained, still needs to be shared.
