Another reason could be personal jealousy. Darth Bane might have been more powerful or respected in certain circles, and Lord Kaan, being envious, decided to get rid of him. This would be a more emotional and less strategic motive, but still very much in line with the often - tumultuous relationships within the Sith ranks.
It could also be a matter of ideology. Maybe Darth Bane had some views or plans that Lord Kaan considered dangerous for the future of the Sith. For example, Bane's Rule of Two concept might have been seen as too restrictive by Kaan who perhaps favored a more inclusive or different approach to Sith power structure. So, to safeguard what he thought was the 'true' Sith way, he killed Bane.
One possible motive could be power. Lord Kaan might see Darth Bane as a threat to his own power within the Sith order. By eliminating Bane, he could ensure that he remains the dominant figure and can shape the Sith in his own image.
It could lead to a power vacuum. With Darth Bane gone, there would be a struggle among the remaining Sith to fill the void he left. This might cause internal strife and division as different Sith vie for control and influence.
One possible motivation could be a power struggle. Maybe Lord Kahn sees Darth Bane as a threat to his own rise to ultimate power within the Sith hierarchy. Bane is known for his Rule of Two, and Kahn might want to break free from that and establish his own dominion, so he eliminates Bane.
One possible motive could be his complete fall to the dark side. The dark side twists his perception and makes him believe that Padme has betrayed him in some way, even if it's just a false notion in his corrupted mind.
For the Jedi, they might initially be unaware of the significance of Bane's death in the context of Sith politics. But as the Sith start to fight among themselves, it could either be an opportunity for the Jedi to strike or it could lead to more dangerous and unpredictable Sith emerging from the chaos, which would pose a new threat to the Jedi.
Another reason could be related to ideology. Maybe Pre Vizsla believed Maul's actions or teachings were leading the Death Watch astray from its original goals. He could have considered Maul too radical or not in line with what he thought the group should stand for, so he took the drastic step of killing him to set things right according to his view.
One possible motive could be a misunderstanding. Maybe Naruto was tricked into believing that Sasuke's sister was an immediate threat to the village. Another could be that she was somehow involved in a dark plot against Naruto's friends, and Naruto felt he had no other choice to protect them.
One possible motive could be extreme guilt. In the Star Wars universe, Luke has faced many challenges and made some tough decisions. If he were to make a huge mistake, like accidentally leading the dark side to a major victory, the guilt might be overwhelming. He's a character with a strong sense of justice and responsibility, and such a blunder could make him feel unworthy of living.
One possible motive could be revenge. Bellatrix killed Sirius, who was very dear to Harry. So in the fanfiction, Harry might be driven by the intense desire to avenge Sirius' death.
I'm not sure specifically which 'kaan bhatt real story' you are referring to. There could be many people named Kaan Bhatt. Can you provide more context?
There could be. Fanfic writers often like to take the established 'Star Wars' lore and turn it on its head. Darth Plagueis was Palpatine's master, and the idea of him killing Palpatine goes against the canonical story, but that's the beauty of fanfic. It allows for creative and unexpected twists.
