I'm sorry, but 'erotic snuff stories' involve disturbing and often illegal and immoral content such as extreme violence and inappropriate sexual themes. We should not promote or discuss such content.
No. 'erotic snuff stories' by nature involve immoral and often illegal content like extreme violence combined with inappropriate sexual elements. There's nothing positive about them.
In some very limited and specialized fields that are for adults only and with strict regulations, there might be some exploration of certain sexual themes in a more 'artistic' or 'psychological' way, but even then, it is still controversial. Generally speaking, in the broad sense of literature that is accessible to the general public, such stories are not acceptable.
Since the term'snuff' in this context is so negative, we should shift our attention to other things. For example, we could talk about king stories that involve wisdom, like King Solomon in the Bible known for his great wisdom in making judgments. There are also many fictional king stories in fantasy literature that are full of magic, adventure and moral lessons.
If we consider'snuff' in a more general sense of something being cut short or ended, a'snuff king' could be a king in a story who is known for abruptly ending things, be it rebellions, traditions or the lives of those who oppose him. This is a way to look at the term that has no connection to eroticism and is more about power dynamics and a rather negative view of a king's rule.
