I think that this is scaled too large. There are plenty of more personal situations that one can use to attempt to make the same point, because the basic premise is dirt simple: Does it make sense to inform someone of a situation that is likely to cause them fear, stress, sorrow or whatever intense emotion you care to name, when they have no agency over the situation, and once the occurrence is complete, whether they knew in advance is basically moot?

In the end, this comes across as a variation on a Trolley Problem, where there isn't really a "correct" answer, so the point is to better understand one's own thought process. I suspect a more down-to-Earth scenario would make this useful for that.
