Dystopian, literally by definition, is not allowing people to die.

I think people who are using "literally" as emphasis instead of really meaning "in a literal sense" are criticized too much. It's just how language evolves.

But saying "literally by definition" for something that has nothing to do with the definition doesn't feel like emphasis, it feels like lying.

"relating to or denoting an imagined state or society where there is great suffering or injustice."

Sounds pretty literal to me. Not letting a suffering person die.
