TL;DR: Telling a reader what to think will just irritate them.
On morality in fantasy and science fiction
This a repost of an article I did that evaluates morality /ethics in science fiction and fantasy. The same lines of argument can be applied to any genre but my knowledge is in SFF. This is the moderately less contentious and shorter version. 😉
Ultimately, you want readers to buy your book (really just a consumer product although I secretly pretend it is a work of art) and it doesn’t matter what their views are as long as they buy your book. Not everyone like it, but hopefully some will love it. Under no circumstances would I ever recommend talking down to the reader, any reader. Soap boxing your political (e.g. moral) beliefs is really a no-no. Make the readers emote but do not irritate them.
In this essay I review the judgement of morality as given by the author from the evidence of their texts. I will state my own preferences and understanding of the texts used, and come to a conclusion that is consistent with my appreciation of said texts.
