One reason could be more intense battles. For example, in a fanfiction scenario, if certain key battles like Stalingrad or Normandy had been even more fiercely fought. Maybe the Axis powers had stronger defenses or the Allies had less effective strategies initially. Another aspect could be the introduction of new and more deadly weapons earlier in the war. This could lead to higher military casualties on both sides.
One reason could be the alteration of major battles. For example, if in the fanfiction the D - Day invasion fails catastrophically, it would lead to a huge number of Allied deaths and a shift in the war's momentum towards the Axis. This would likely cause a domino effect, with more battles resulting in heavier losses as the Allies struggle to regain the upper hand.
The post - war world would be much more devastated. Economically, more military deaths would mean a greater loss of human resources. Countries would have a harder time rebuilding as there would be fewer able - bodied men (and women in some cases) to contribute to the workforce. For example, the rebuilding of Europe would be far more challenging.
The post - war world in such a fanfiction would likely be more devastated. Economically, it would take much longer to recover. With more deaths, there would be a shortage of manpower to rebuild industries and infrastructure. For example, countries like Germany and Japan that were rebuilt after the real World War 2 might struggle even more in this fictional scenario.
One possible reason could be political. After the war, the villages might be restructuring and Naruto, with his great power, could be seen as a threat. Another reason might be related to the secrets he knows. Maybe some powerful figures don't want him to expose certain things. Also, his Jinchuuriki status could play a role. People might still be fearful of the power within him even after the war.
One reason could be that he feels burdened by the expectations and the weight of his newfound peacekeeping role. He might want to escape the constant pressure and find himself. Another possibility is that he discovers a new threat during the post - war reconstruction and decides to go into hiding to investigate it without causing panic. Maybe he also has some personal issues related to his relationships, like feeling estranged from his friends who have changed after the war, and he needs time alone to sort things out.
The plot could involve Tony starting to sell his high - tech weapons to the highest bidders without considering the consequences. He might get involved with some shady underworld characters who are interested in using his weapons for their own evil purposes, like starting wars or assassinations.
The possible reasons in the Burari deaths real story are complex. Superstition seems to be a big factor. The family might have been influenced by some local or self - created beliefs. Also, there could have been some psychological factors at play. Maybe they were in a state of collective delusion. They seemed to be following a set of rules or instructions that were not based on rational thinking, as seen from the evidence of the writings in the house.
One possible reason could be their different life goals. Sasuke has always been on a journey of self - discovery and revenge in a way. Sakura, on the other hand, is more focused on building a family and a stable life. In the fanfiction, this clash of ideals might lead to their divorce. For example, Sasuke might feel that his pursuit of power or understanding his clan's past still takes precedence over his family life with Sakura.
In certain fanfiction scenarios, Harry could leave the wizarding world to explore other magical realms or non - magical places. He may feel that his growth and understanding of magic and life are restricted within the wizarding world he knows. Maybe he meets a group of people from outside the wizarding world who offer him a new perspective and a chance at a different kind of life.
One reason could be that she feels disillusioned with the wizarding world's politics. After all the wars and power struggles, she might just want a simple, Muggle life away from all the chaos.
