As a purely hypothetical scenario of direct analogical relevance to real life, it is of interest to precisely the degree that it is an accurate analogy;

Analogies in moral discussions can serve the purpose to illuminate and identify relevant principles, but generally they just meta the argument from "is X Moral" to "Does the analogy properly map in the relevant aspects?" And that's on a good day. Normally, it's more of a "that's not the same situation", "is so", is NOT"...
