That is two scenarios where garbage is disposed of. At no point is the garbage status questioned: because it is established it is garbage.
I don't think that thought experiment refuted anything.
Nazis are humans. Humans who perpetuate crimes against humanity. The crime against humanity that is Nazism carries the death penalty--as it should. It's a ideology predicated on lives not mattering.
There is a reason one of the most prominent acts of Nazi leadership is suicide.
Oof, let me rephrase:
I don't think the thought experiment reinforced or helped explain the refutation of "Nazi lives don't matter" with the claim "Nazi lives do have value."
That should've been clear, and I think it is for any reading audience? So, uh, yeah.
