My dilemma.
(Note mentions of mature content)
While writing my story, "I Woke up in the Forest and Became Childhood Friends with the Future Champion," Chapion's Childhood Friend for short, I came up with a genuinely evil character. They are so disturbing in their actions that their existence alone would be grounds enough for a Mature Rating. However, this might not be an actuate descriptor of how deprived this character is. So, let me put it this way: if I were to add them in in their full glory, at the start of the chapter, I would have to add content warnings for Incest, Rape, Necrophilia, and Petophelia. I don't need one for murder because, of course, I don't. In my opinion, they are likely one of the most disturbing characters in fiction.
Now, I'm debating whether to include them in their full, unadulterated horror, not to hide anything from the reader but to reveal the depravity I thought up while walking a dog.
Your thoughts and input would be greatly appreciated.
