A JW friend of mine visited the site of Auschwitz-Berkenau and bought a book on JWs in Auschwitz which documents which JWs were in the camp, which ones died, and what they did while they were there. Known as honest and industrious workers, a lot of them, especially women, were employed as domestic help in the homes of the SS commanders. This is well documented. These women looked after the kids, did the housework and ran errands to the shops and other places in town.
By contrast, there were several small religious groups in the Soviet GULAG who like the JWs were considered decent workers who refused to work for the camp commanders. Even non-religious (at the time) prisoners refused to work for the commanders because it was considered immoral. The writer Alexandr Solzhenitsyn himself when he was a prisoner refused to work on a project that would harm his fellow Soviet people.
And like the bosses of the GULAG, these SS commanders were responsible for the hideous oppression going on around them. They knew damn well Jews were being sent to the gas chambers; they were the ones running it! And JWs went and worked in the homes of these murderers. Of course I shouldn't judge the the JWs because they were faced with painful death and this a way to snatch some more life. I can't help thinking though, that by helping the SS they were collaborators in what the SS were doing at Auschwitz. Compare that to the people who lost their lives or health in the GULAG because they wouldn't help in the oppression of fellow humans. By collaborating with the SS as domestic help, were they not party to the work of murder and oppression the SS were doing?
