The Chosen Ones

ive never seen anyone slay dragons. lets take them out too. lets also take out magic.

Let's imagine you wrote a work of speculative fiction not based on reality. And thus there'd be such things like magic, dragons, FTL travel, etc... Since it's not based on reality, it's fine.
However, if you wrote it in an existing language and you decided to invent a new word (or a new meaning of an existing word) to refer to something already present in reality, then you'd be obviously criticised, as it derails from the original language. Made-up and wrongly-used words have absolutely zero value in works of fiction.
Apply this to the 'morality' word here.
