What are some possible reasons for Snape to turn against Dumbledore in fanfiction?

In some fanfictions, Snape could have his own personal vendetta against Dumbledore. Maybe Dumbledore has wronged Snape in the past, and when he sees Harry as a potential victim of Dumbledore's schemes, he decides to help Harry. Another reason could be that Snape has a new understanding of the prophecy and believes that Dumbledore's way of handling it is wrong, so he steps in to help Harry.

There are indeed. Fanfiction often takes the existing characters and relationships and turns them on their heads. In this case, Snape helping Harry against Dumbledore could be a result of Snape's long - held grudges against Dumbledore's actions or decisions. It's a creative way to explore the gray areas of these beloved characters.

Maybe Dumbledore made a decision that put Harry in great danger without his knowledge. For example, sending him on a dangerous mission without proper preparation.

One reason could be that Snape has his own complex sense of loyalty. He may feel that Dumbledore's plans for Harry are too dangerous or not in Harry's best interest in some ways. He has a long - standing relationship with Harry's mother, Lily, and perhaps through that connection, he wants to safeguard Harry from any harm that might come from Dumbledore's actions or decisions.

One reason could be a change in Dumbledore's personality. If he's depicted as being cold or distant in fanfiction, Harry, who knew him as a mentor figure, might not like it.

One reason could be a misunderstanding. Maybe Harry discovers some actions of Dumbledore that seem wrong at first glance, like the way he's been handling secrets about Harry's past or Hogwarts' safety. For example, Dumbledore's decision to keep Harry in the dark about certain prophecies might make Harry feel betrayed and lead to a conflict.

One possible reason could be a difference in ideology. Maybe Harry starts to question Dumbledore's decisions regarding the war against Voldemort. For example, Dumbledore's secrecy about certain things might make Harry feel left out and manipulated. Another reason could be personal pride. Harry has grown into a powerful wizard and may not want to be under Dumbledore's constant guidance and control any longer. He might think he can handle things on his own better. Also, it could be due to the influence of other characters. If some new friends or allies have different views on Dumbledore, they could sway Harry's opinion.

In some fanfictions, it could be related to Snape's loyalty to Dumbledore. If Snape believes Harry is endangering a secret plan that Dumbledore has set in motion, he might punch Harry to stop him from doing something stupid. For example, if Harry is about to reveal a crucial piece of information to the wrong person.

One possible reason could be the extreme stress he endures. In many fanfictions, Snape has to constantly balance his double - agent role during the war. The pressure of keeping his true loyalties hidden from Voldemort and his Death Eaters while also trying to protect the students at Hogwarts can be overwhelming, leading to a collapse.

One reason could be that Snape believes Hermione has knowledge that is dangerous if it falls into the wrong hands. So, he kidnaps her to keep her safe until he can figure out what to do with that knowledge. Another possibility is that he is being controlled by some dark magic or an outside force which compels him to take her against his will.
