Some gods might be indifferent. They might see Percy as just a mortal who has outlived his usefulness. For instance, a god who only cares about power and has no real connection to Percy would simply ignore his request.
Then there are the gods who might be angry. If they see Percy's request as an insult or a challenge to their authority, they could punish him instead of granting his wish. For example, a god like Zeus who is quick - tempered might react harshly.
There could be gods who are sympathetic. They might try to talk Percy out of it, like Athena who values wisdom and life. She could offer him solutions to his problems or a different perspective on his situation.
Some gods might be indifferent. They are used to mortals' pleas and may see Percy's request as just another desperate cry from a human. For instance, Zeus, who is often portrayed as self - centered, might not care much about Percy's pain and simply ignore the request.
One reason could be extreme despair. Maybe he has faced so many hardships and losses that he feels there's no way out. For example, if he has lost many friends in battles against powerful foes and he blames the gods for not protecting them better.
Tsunade would probably be shocked at first. Naruto is like family to her. She might immediately refuse and try to talk some sense into him. She could say something like 'Naruto, you're stronger than this. There's always a solution to every problem.'
The gods might show their protection in various ways. For example, they could directly intervene in battles Percy is in, using their divine powers to shield him from harm. They might also send him signs or omens to guide him away from danger.
Perhaps he has lost too many people close to him. If his friends, like Annabeth or Grover, were to die in a particularly tragic way, he could be so grief - stricken that he no longer wants to live in a world without them. He might think that death is the only way to escape the pain of their loss.
Maybe Percy unknowingly breaks some ancient and very strict laws of the Gods. For example, he might interfere with some sacred rituals or places that are off - limits to mortals, even demigods like him. In the fanfiction world, the Gods could be very unforgiving when it comes to such violations and decide to kill him as a result.
They might react with shock, as they may not have fully realized the extent of the danger Percy has faced. Some gods could be impressed by his survival and show newfound respect.
There could also be friends who are so loyal to Naruto that they would consider following his request if they truly believe it's for the greater good. However, they would be deeply pained by it. Kakashi, for instance, might understand Naruto's selfless nature but would also struggle with the moral and emotional implications of taking his life.
Perhaps he has been through some sort of mental and emotional breakdown. Maybe he has lost too many battles, seen too many friends die, and he feels that he is a burden or that his death would somehow bring peace to his troubled mind. It could also be related to some prophecy or dark secret he has discovered about himself that makes him think death is the best option for everyone.
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.
