Yes, it's exactly the kind of sadistic psychological abuse you would expect from n@zis. Shades of 'Sophie's Choice', which was apparently inspired by true stories from the concentration camps:

'A central element of the novel's plot, the personally catastrophic choice referred to in the title, is said to have been inspired by a story of a Romani woman who was ordered by the Nazis to select which of her children was to be murdered, which Styron attributes[citation needed] to Hannah Arendt's Eichmann in Jerusalem.[4] However, Ira Nadel claims that the story is found in Arendt's The Origins of Totalitarianism.[10] In that book, Arendt argues that those who ran the camps perpetrated an "attack on the moral person":

"Totalitarian terror achieved its most terrible triumph when it succeeded in cutting the moral person off from the individualist escape and in making the decisions of conscience absolutely questionable and equivocal. (...) Who could solve the moral dilemma of the Greek mother, who was allowed by the Nazis to choose which of her three children should be killed?[11]"

Arendt cites Albert Camus' Twice a Year (1947) for the story, without providing a pinpoint reference.[12][13][14]' - https://en.wikipedia.org/wiki/Sophie%27s_Choice_(novel)#Plot_inspiration

They want to disclaim responsibility as perpetrators and enlist the victim themselves in the murderous process, making them feel culpable even though it can never be a real 'choice' under such extreme duress. I'm sure they would present it as some wonderfully humane thing too - "See, we got them to go off somewhere by themselves to meet their fate instead of blowing up the whole family". It's all so incredibly sick, and I can't imagine what it must be like to have that as your last memory of a family member before the fash came and murdered them.
