Well, in most of the established 'Harry Potter' lore, Ginny is in love with Harry, so a 'ginny tries to kill harry fanfiction' is a very out - of - the - box concept. It could be a dark exploration of an alternate universe where Ginny has been corrupted or influenced by some dark magic or external force that makes her turn against Harry. Maybe the writer wants to explore the extreme consequences of a character going completely off - their - normal - path.
Merlin could use his magic to show Harry visions of a better future. By giving him hope, Harry might change his mind. For example, Merlin could show Harry how his actions in the future would lead to great good.
One possible reason could be jealousy. Maybe she sees Harry getting too much attention or having relationships with other characters that make her feel left out and envious, which then turns into hatred and a desire to kill. Another reason might be a misunderstanding. Harry could be involved in some secret mission or activity that Ginny misinterprets as something harmful, leading her to think he's a threat.
In this fanfic, Vernon might be driven by his hatred for Harry and sees the baby as an extension of that. It could lead to a tense and dangerous situation for the baby and Harry's attempts to protect it.
One possible reason could be the overwhelming burden of his destiny. Harry has faced so many challenges and losses throughout his life. The death of his parents, the constant threat of Voldemort, and the weight of saving the wizarding world might have made him feel so tired and hopeless that he contemplates taking his own life.
In 'amy tries to kill sonic fanfic', it might be that Amy has been tricked by an enemy. The enemy could have made her believe Sonic has done something really bad. So, out of a sense of justice or revenge, she tries to take Sonic's life. However, it's all a big ruse, and Sonic has to figure out how to make Amy see the truth before it's too late.
I don't know who created this particular fanfic. There are so many Sonic fans out there creating various fanfics, and it's hard to pinpoint the creator without more information.
Peter could be a disgruntled noble in the fanfiction. He might be someone who has been overlooked for promotions or honors by the emperor, and this has led to his resentment and desire to kill the emperor.
The way the fanfiction portrays his relationships can also show despair. If his friends try to reach out but he shuts them off, it's like he's in a deep hole of despair where he doesn't believe anyone can help. And his actions, such as isolating himself in a dark place, could be symbolic of his state of depression.
Maybe in this fanfiction she experiences a great loss, like the death of a loved one in a very tragic way. For example, if Ron or Harry were killed in a battle and she blamed herself for not being able to prevent it. This overwhelming guilt could be a reason for her to try to kill herself.
