How is dystopian fiction present the power of fear? How could dystopian or utopian fiction be used to manipulate readers?

Dystopian fiction presents the power of fear very realistically and dystopian or utopian fiction could be used to manipulate readers by scaring them off with the possibility of what could happen (bad). Dystopian fiction presents a future where many people suffer and live in misery because of something taken to the extreme. Dystopian or utopian fiction, therefore, manipulates the reader to not do what caused the misery in the story. Dystopian fiction exaggerates existing problems in our reality to show readers what could happen if society continues down a certain path. Both utopian and dystopian fiction is used to warn readers about the risks of attempting to alter society in any way. "Dystopian authors argued that the pursuit of perfection will inevitably lead not to 'no place' but to a 'bad place', because of flaws within the system" (Ostergaard, Commonlit). So this kind of future is a fear for the people and it is a dangerous world. It is a kind of future where no one wants to live in.
