Nuremberg trials.
But you know, I have to say I don't agree with people not using research stemming from inhuman experiments. The damage is done, not using the knowledge obtained would make it pointless. It's kinda like synthesizing artificial blood, testing it on humans, and then when/if a subject dies, people say "this didn't meet the criteria" and throw it away.
Meanwhile, the angry spirits of those who died to provide the knowledge and those who COULD have benefitted from the result and died too get a bigass FUCK YOU.
I just don't believe in retroactive morality (which, in a way, is like saying I don't believe in morality itself, since morality relies on hindsight to judge what is moral or not).
