The village might be in chaos. If Naruto starts to control people, he could disrupt the normal order. For instance, he might force people to do things against their will, which could lead to economic and social problems. The villagers who were once his supporters might turn against him, and the whole structure of the Hidden Leaf Village could be at risk of falling apart.
On a larger scale, other villages might see Naruto's new power as a danger. This could lead to wars or alliances against the Hidden Leaf. Other ninja villages would be worried that Naruto could use his power to control their ninja and gain an unfair advantage. So, it would not only affect Naruto's relationships within his own village but also the balance of power in the entire ninja world.
One consequence could be that his friends start to fear and distrust him. After all, controlling people goes against the principles they uphold. They might see him as a threat and try to stop him, which could lead to a lot of conflict among them.
One consequence could be that his friends start to fear or distrust him. After all, mind control is a very invasive power. They might worry that he could use it against them at any time.
One possible consequence could be that Naruto is ostracized by some in the ninja world. Since controlling blood is a rather strange and perhaps 'creepy' ability to some, they might view him with suspicion or fear. This could lead to him having to prove himself more often in battles and interactions.
One consequence could be that it makes him an outcast. Controlling the dead is often seen as a dark and forbidden art, so his friends and allies might be afraid of him or turn against him.
In some fanfictions, controlling the Kyuubi chakra might change Naruto's appearance. He could have some physical features related to the Kyuubi, like red - tinted eyes or a more ferocious look when using the chakra. Also, his relationships with others might be affected. Some might be in awe of his new power, while others could be afraid of him.
One consequence could be that it disrupts the natural balance. If Naruto isn't careful, his weather control might cause floods in some areas or droughts in others. For example, if he overuses his power to create rain, it could lead to excessive flooding.
There could also be environmental consequences. If Naruto isn't fully in control of his flood - controlling ability, he might accidentally cause damage to the local ecosystem. For example, he could disrupt the natural flow of rivers and flood areas that are important habitats for animals and plants.
One consequence could be moral. They would have to deal with the ethics of controlling the dead. Are they disturbing the natural order? This could cause a rift between them and some of their friends and allies who might not agree with such a practice.
One consequence could be a change in the school's power structure. If Harry controls Hogwarts, the old hierarchies might be challenged. For example, the influence of some traditionalist teachers could decrease. Another consequence might be a shift in the curriculum. Harry may introduce more practical and combat - related magic lessons, given his own experiences.
One consequence could be that it disturbs the balance of the ninja world. The dead are supposed to rest, and by controlling them, Naruto might be messing with the natural order. This could lead to other ninja clans or villages seeing him as a threat.
There could be a power struggle within the wizarding world. Some pure - blood families who have long held influence in the Wizengamot might oppose Harry's control. This could lead to internal conflicts, maybe even a split in the wizarding community between those who support Harry and those who don't.
