Well, in general, if we were to hypothetically analyze it, a sociopath in an 'erotic story' might be depicted in a very distorted way. Sociopaths in real life have serious issues related to how they interact with others. But in such a fictional and inappropriate context, it might just be used to create some sort of 'edgy' or 'taboo' narrative which is not a proper way to represent mental health conditions.
In the light novel, Ayanokoji is clearly the more intelligent one. He has a unique ability to analyze situations and people's motives deeply. Ryuen often falls into Ayanokoji's traps because he doesn't fully understand Ayanokoji's true nature. Ayanokoji can anticipate Ryuen's moves and counter them effectively, while Ryuen struggles to keep up with Ayanokoji's complex thinking.
No. Naruto in the original series is a character full of positive traits like determination and kindness. While fanfiction can take different turns, most fan-authors still try to stay true to his core nature and not make him a sociopath.
One aspect of 'Story of a Sociopath: A Novel' could be the psychological study it presents. It may take the reader through the development of sociopathic traits in the character. Maybe the story starts with the character's childhood, showing early signs of this disorder, like cruelty to animals or lack of emotional response to others' pain, and then progresses to how it affects their adult life.
It's possible that in some very niche or dark fanfictions, Naruto Shikamaru could be presented as a sociopath. But this is a huge deviation from his canonical character. In the original series, Shikamaru is known for his laziness on the surface but deep down he has a strong sense of duty and connection to those around him. Fanfiction writers may use the idea of him being a sociopath to add an edgy or different perspective, but it goes against the essence of who he is in the official story. For example, his relationships with Naruto, Choji, and others show his capacity for friendship and loyalty, which is the opposite of sociopathic behavior.
Yes, in some fanfiction, Harry can be portrayed as a sociopath. This might be due to certain plot twists where he has endured great trauma, like the loss of his parents in a more extreme and dark way. It could also be an exploration of how power and isolation in the wizarding world could potentially warp a person's personality, turning them into someone who lacks empathy, which is a key trait of a sociopath.
When Ayanokoji says 'I'll use any means necessary to achieve my goal', it reveals his somewhat ruthless side. He is not bound by conventional moralities when it comes to reaching his objectives. In the light novel, this could be a result of the cut - throat environment he is in. However, it also makes him a complex character as readers are left to question whether his actions are justifiable or not.
