"To be honest, I'd say Naruto has some of the most believable villains in the anime world. The series always goes to great lengths to delve into the backstories of its villains, and each one has their own unique and interesting motivations for what they do. Off the top of my head, I can think of Itachi, Sasori, Orochimaru, Zabuza and Haku, Kabuto, Gaara (for a while). None of them are just insane, bloodthirsty monsters. They all have fleshed out motivations and backgrounds that drive them to do what they do."Yeah, agreed. Naruto does kind of give TOO much backstory though.
