This kind of fanfic is inappropriate because it can be very disturbing for fans, especially younger fans who are attracted to the Naruto series for its action, adventure, and positive character interactions. It can also damage the reputation of the fan community as a whole by promoting such unethical content.
Writing or promoting fanfics with inappropriate and unethical content such as molestation is unacceptable. There should not be any such fanfics in a proper and respectful fan community.
First, be vigilant when searching for fanfics. Avoid websites or sources that are known for hosting inappropriate content. Second, stay within the community guidelines of official Naruto fan communities which usually prohibit such unethical content.
One possible reason could be for his safety. Konoha is a well - protected village with many skilled ninja. She might believe that leaving him there would ensure he has the best chance at survival and growth as a ninja. Also, she may have some mission or obligation that forces her to leave him behind, perhaps something related to the greater good of the village or the ninja world in general.
In some fanfics, there could be a misunderstanding. Suppose Kushina did something that Naruto misinterpreted as harmful to him or his friends. This misinterpretation could lead to his hatred. For example, if Kushina was involved in a mission that Naruto thought put the village at risk, but in reality, she had no choice.
Maybe in this fanfic, the author wants to create a unique and dark plot. Kushina might be made to hate Naruto due to some kind of misunderstanding. For example, she could be misled to believe that Naruto has some connection to a great evil that she is against.
Maybe in this fanfic, there has been a misinformation spread about Naruto that makes Kushina believe he has done something unforgivable. For example, if false rumors say that Naruto is involved in something evil, Kushina might start to hate him without knowing the truth.
One possible reason could be for Naruto's safety. Maybe she has to go on a dangerous mission and believes Konoha is the safest place for him. Another reason might be that she is forced by some powerful enemies who threaten Naruto's life if she doesn't leave him in Konoha.
In some really complex fanfic plots, there could be a prophecy or some sort of ancient power play involved. Suppose there is a prophecy that Naruto will bring great destruction in the future, and Kushina is made aware of it through some dark magic or secret organization. She might think that betraying Naruto now is the only way to save the village and the world, even though it goes against her motherly instincts. This would be a very convoluted and interesting take on the idea of her betrayal.
One reason could be the desire for more content. The official Naruto story has limits, but fanfic can offer countless new stories. For example, she might want to see different versions of her relationships with other characters.

You can search on well - known fanfic platforms and filter by ratings and reviews to find ones that focus on their relationship in a positive, non - offensive way, such as stories about Kushina's motherly love for Naruto or their family bonds in the Naruto universe.
