Should unsavory but otherwise scientifically correct experiments lead to retractions?
In human and animal work, the Declaration of Helsinki was written in 1964 and was designed to provide ethical oversight of medical research. Work that was done without proper ethical oversight cannot be published in most reputable journals. If it was somehow published, it would be retracted. Most journals require a statement in the paper that good research practice was followed. Other fields presumably do not require such statements since the frequency of such unethical and dangerous behavior is rare. That said, research that wad conducted in a manner that was more dangerous than necessary should not be published, and if published should be retracted.
