Depends on what three purpose of the writing was. There's an entire genre of work that is entirely imagined works. Fiction, as a category, is quite popular, even. It's when it leaks back to the real world that there's issue. If I tell a heartwarming story about a mother and her daughter going on a trip together and it makes people feel better, who cares if it's entirely fictional? It's when that mother or daughter is someone you know, or is someone famous, that it affects anything. Aka go read /r/AmItheAsshole/ for entertainment value, but don't have it need to be true for it to give you feels.

I watched the Spiderman movie the other day and it provoked real emotions in me despite the story being totally fictional.
