Danzo quotes from Naruto: Shippūden

Danzo

I just hope he's not too deeply rooted in the pacifism of that pushover Sarutobi. The gutless teachings of the Third, who hated all manners of disagreement, just as the Third Hokage was rooted in the teachings of your grandfather.

Danzo

[To Sai] That smile. Tsunade has already approached me about this. But be sure that you remember Sai, emotions only generate hatred, and hatred breeds nought but conflict.

Danzo

[Last words, regarding the Third Hokage] You were the tree leaf upon which light shone. I was nothing but a foundation hidden in darkness.

Danzo

The princess did become Hokage after all. With Katsuyu's techniques, she'll be able to prevent total annihilation, but there will still be some causalities. Those are a necessary sacrifice for us. In order for me to become Hokage.
