yeah i knew it to...but in the same time you will be sad that your father did it and many shinobi from other village hate yondaime cause he was strong and if they knew about naruto they will kill him, or use himI think its not fair to not tell naruto abot his father
naruto lived a terrible life coz of the kyuubi sealed in him
if ppl knew he was the fourth son maybe they would have treated him wit respect and stopped bein so harsh to him afterall he is the son of person who saved them all
