One possible reason could be Snape's past experiences. Maybe he had a difficult childhood himself and doesn't know how to handle having a son. He might project his own insecurities and traumas onto Harry. Another reason could be that he sees too much of Harry's father in him. Since Snape had a long - standing feud with Harry's father, seeing those traits in Harry could trigger his hatred.
Well, it could be that Snape is simply a very complex character in this fanfiction. He might hate Harry as his son because he has high expectations for him that Harry can't meet. Snape is known for his strictness and if Harry doesn't conform to the standards Snape sets for his 'son', it could lead to hatred. Also, perhaps there are some dark secrets in Snape's family history that make him act this way towards Harry.
In this fanfiction, Snape's hatred for Harry as his son could stem from envy. Snape might envy Harry's natural talent and popularity among his peers. Despite being his 'son', Snape may feel overshadowed by Harry. Additionally, the power dynamics at Hogwarts could play a role. Snape is a teacher and having a 'son' like Harry who constantly challenges the status quo and gets into trouble might make Snape resent him. And let's not forget that Snape has his own loyalties and goals which might conflict with Harry's actions, leading to his hatred.
