@akargeI absolutely avoid stories with a "Snuff" code.
I believe that "Snuff" also includes Murder after "sexual" acts upon the victim. Or for those Insane people for whom violence resulting in death "replaces" sex. I would complain Strenuously to the author, and if there was no response, to Lazeez about a story containing such without the Warning: Snuff!
I write stories with significant violence and death, and have read many stories with lots of, sometimes graphic, violence and death.
There is a "fine line" at least for me, between "sick" (or silly) violence in some "Mack Bolan" books, and a few westerns by an author whose name I can't recall but recognize when I see his copious books in stores. Scenes similar to "the 5.56mm tumbler shredded his flesh like a burrito stuffed into a La-Machine spraying blood and gore like modern art..."
During scenes depicting violence, or the aftermath of violence I often depict the horrid smells, voided bowels, stench of burnt flesh, and a realistic amount of blood. Sounds too. Violence may be necessary, or not; up close it is almost always terrible to witness. Most corpses are messy and undignified.
I try to get my readers to understand there are consequences for the participants and witnesses of the violence I depict. Not a "PG rated" "A-Team" (the TV show) where no one is ever killed, and no blood spilled.
I don't like stories that depict blood and gore to titillate "teenage boys" who've never seen actual violence and seem to feel it would be "fun"
Nothing I write can truly depict the violence I have seen. I know that many people have seen much worse.
Still, I hope to "educate" my readers, at least a bit, by some of the realities of combat and violence.
I try to depict my characters as being fatigued, miserable, often in an unpleasant climate, and that is before the violence begins.
Depictions of violence, similar to the blurred boundaries between "Art" and "smut" are difficult to define, but most people tend to recognize it when they see it.
