I dislike the fact that all of the chapters have so few pages but all mangas are preety much like that xd
sorry to say but jiriya is partly to blame because of jaraiya nagato got the idea he was the person who would bring peace to the world and through all nagato's experiences not just his experience with danzo made him become the "i want to destory everything to bring peace" guy. so stop having a unjustified hatred for danzo most of the things he did was to protect the village but it didnt turn out how he hoped.1. Nagato is awesome, following Jiraiya's teaching together with Yahiko, tyring to bring peace with Akatsuki.
2. Hanzo of the Salamander makes a peace treaty with Akatsuki.
3. Danzo talks to Hanzo and convinces him to accept his offer.
4. Hanzo of the Salamander (+ Danzo) betray Akatsuki and Nagato.
5. Yahiko get's killed, Nagato go's nuts and becomes evil retard.
6. Nagato kill's Jiraiya by outsmarting him during combat, killing his seinsei that loved him, thaught him so much, trained him and cared for him.
Danzo = Cause of so much Sorrow, not even funny.
Danzo was a pathetic failure of a Shinobi, always failing to compete with the Third Hokage and at the end he got killed by an Uchiha Avenger while running away like the cowardly dog he is.
