no he just doesn't care about destroying Konoha anymore beside Pain did it and they are in the midst of rebuilding so he can't brag about destroying a village that is basically a ghost town it's like fighting an old man
No. He's being realistic. Madara said the same. I'm sure Oro and Madara appreciate its existence, but they think it was a mistake for a good guy (Tobirama) to create.
oro is no longer a strong factor so best thing for him is to make the 2 power pieces take each other out basically telling the first that madara is loose..
