Everyone enjoys seeing someone else get their comeuppance (which may or may not be the word you were looking for). Is that something to be proud of? Certainly not, but neither should it be particularly shocking.

If you wanna wage a campaign against this, then you might as well start with the term "unicorn", which is itself subtly mocking; after all, unicorns aren't rare: they are non-existent. The root term implies the same thing that bothers you about the derived -corpse: these valuations are irrational, and a reckoning will be had.
