Harry could react with anger. He is a strong - willed character. So, he might confront Snape about his hatred. He would demand to know why Snape is treating him this way when they should have a father - son relationship. This could lead to a series of intense arguments between them.
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.
Often, it starts with intense dislike. Snape is constantly critical of Harry in class, deducting points for the slightest mistakes. Harry, in turn, sees Snape as a bully. As the story progresses, there might be small moments of grudging respect, like when Harry realizes Snape's intelligence in potions, but the overall hatred remains for a long time.
He may also get angry. Harry has a strong sense of justice and self - worth. Snape's rejection could be seen as unfair in his eyes, especially if he has started to develop some sort of positive feelings towards Snape. So, he might lash out at Snape or even try to prove him wrong by becoming more independent and successful on his own.
One possible reason could be his lingering resentment towards James Potter, Harry's father. Snape and James had a long - standing feud during their school days. Since Harry looks a lot like James, Snape might be transferring his old grudges onto Harry.
Snape might be motivated by a desire for redemption. He has a complicated past, and saving Harry could be his way of making up for all the bad things he has done or been associated with. Additionally, he might see a bit of himself in Harry's situation, as he also had a difficult childhood, and this empathy drives him to act.
