What are the possible motives for Hiccup to kill a dragon in fanfiction?

One possible motive could be jealousy. Hermione is highly intelligent and often outshines Draco in academics. In a twisted version of a rivalry, Draco's envy could turn into a deadly hatred. Another could be his family's influence. If the Malfoys push him to take extreme actions against Muggle - borns, Hermione would be a prime target.

One possible motive could be jealousy. If Kiba were to gain more recognition in the village than Naruto in the fanfiction world, Naruto's insecurities could drive him to do something drastic like killing Kiba. But this is a huge departure from his usual self.

Differing ideologies during the wizarding war. If James was seen as a threat to Snape's side (even if Snape was on the wrong side, from a moral perspective), Snape could justify killing him. For example, if James was too aggressive in fighting the Death Eaters and Snape thought it would lead to more bloodshed, he might take matters into his own hands to stop James.

One possible motive could be revenge. The Dursleys treated Harry awfully for years, so in fanfiction, he might reach a breaking point. Another could be self - defense if the Dursleys in the fanfiction were to take their abuse to an extreme level.

One possible theme is friendship. The relationship between Hiccup and his dragon is a strong form of friendship. They rely on each other, trust each other, and grow together.

Perhaps Stiles discovers some dark secret about the alpha pack that endangers the entire town or the supernatural world he's a part of. In his sense of responsibility and his unique way of thinking, he figures that killing the alpha pack is the only solution to prevent a greater catastrophe. This can add a lot of depth to the fanfiction story, exploring Stiles' moral compass and his ability to make tough decisions.

One possible motive could be if Sasuke was on a path of destruction that endangered the entire ninja world. Naruto, as the protector of peace, might see killing Sasuke as the only way to stop him. For instance, if Sasuke was about to unleash a powerful and uncontrollable jutsu that would wipe out many innocent lives.

Maybe he wants to change the system. Percy has always been a bit of a rebel, and in fanfiction, he could see the gods' rule as corrupt or unfair. So, killing them could be his way of starting anew and creating a better world for demigods and mortals alike. Another motive could be to prevent a greater evil. If he discovers that the gods are planning something that would destroy the world, he might decide that killing them is the only way to stop it.

Perhaps Sasuke is possessed by some extremely evil entity. And Kakashi, in an attempt to stop the entity from causing more destruction, decides to kill Sasuke. It could also be that Sasuke discovers some dark secret about Kakashi that Kakashi doesn't want revealed, and in a moment of panic and self - preservation, he kills Sasuke.

In fanfiction, Naruto might kill Konoha if he's under some sort of mind control. Maybe an enemy manages to manipulate his thoughts and turn him against the village. Also, if Naruto experiences a great loss because of Konoha's actions or inactions. Say, if his friends are killed due to Konoha's negligence in protecting them, and he blames the village as a whole. Or if he realizes that Konoha's system is so corrupt that it's causing more harm than good to the world.
