Naruto series pretty much gave up giving any of there villains an end to there arc, in favour of replacing them with new villains
Only pain and zabuza really got complete stories, and even pain gets pushed to the side as 'WOAH HE WASNT REALLY A BAD GUY, AND ALSO NOT THE HEAD VILLAINS' Who turns out to be tobi, who turns out to be working for madara, whos being tricked by zetzu, whos actually working for kaguya.
Its a mess.Orochimaru was the big bad for most of original naruto, then just gets killed by sasuke in a random episode and isnt seen for ages,
