Some people might be exploring extreme or dark themes in the realm of creativity. They want to push the boundaries of what can be written in fanfiction.
One reason could be that some fans want to explore the darker aspects of a character's life in a fictional and extreme way. They might think it adds depth or a different perspective to the character. But this is a rather controversial approach.
It could also be a way for some writers to express their own angst or darker emotions through the Naruto universe. By putting Naruto in such a horrible situation like being crucified, they can explore themes of sacrifice, suffering, and the reaction of the other characters in a very extreme way. However, this is not in line with the general positive and action - packed nature of the Naruto series.
It could also be a form of creative exploration that goes way off the beaten path. Maybe the author wants to explore the idea of how the TMNT world would react if such an impossible biological event were to occur. However, it's important to note that this is a very extreme and non - traditional take on the TMNT universe.
One reason could be for exploring different storylines. Fans might want to see Sonic in a more vulnerable situation to add drama and tension to the story.
Some people might be exploring the darker side of human nature through these characters. They want to see how extreme situations can play out between Sasuke and Sakura.
One reason could be a misinterpretation of the characters' struggles. In the original series, the characters face many difficulties, but they always find a way to persevere. However, some fanfiction writers may take those struggles too far and end up with the idea of suicide. Also, there might be a lack of understanding of the impact such content can have on the readers, especially the younger ones.
In fanfiction, authors often explore different relationship dynamics that were not fully explored in the original work. While the idea of Snape getting Harry pregnant is very unorthodox, it could be a way to delve deeper into the characters' emotions and how they might interact in extreme situations. Also, it could be a form of subverting the expectations of the original story's power dynamics and relationships.
Some people might create such fanfics as a form of extreme creative expression. They might want to explore unique or edgy situations for the characters, even if they are not in line with the mainstream view of the characters.
Fanfiction in general should promote positive values. The idea of'male gets raped by monster' is not only inappropriate but also can be very traumatizing for readers. So, in the world of fanfiction that aims to be inclusive and positive, such content is not welcome, and thus not likely to be found in a form suitable for general viewing.
One major negative impact is the potential to trigger trauma in readers who have experienced sexual assault. It can also be highly offensive to religious believers as it desecrates the concept of an archangel. Additionally, it spreads a negative and disturbing message in the fanfiction community which is supposed to be a place for positive creativity.
