>>126262782Nagato is a great villain in my book. Not really a bad guy, just got lost on his way in finding true peace, ultimately sacrificing himself when realizing his wrongdoings.
Zabuza was pretty good too.
Obito was okay I guess, his character fits well with the general theme in Naruto being that nobody really is evil.
Ororchimaru was really never explained on a deeper level.
Kisame had a really brief explanation but I liked his.
The only ones that really didn't had a lot of their backstory and motive explained was Kaguya and Madara. Let's face it, they were pretty shit. Madara was cool as fuck but his motives were weak as fuck.
