Aaaaaas for Sasuke. Let's see. He would probably go with Fruit of Knowledge as well, which will just give a vision of the battlefield they are still on. As for the second though, I don't know. He doesn't want blessings from the gods because fuck them that's why. He wouldn't chance the chance ones either which would only live the apples of forgiveness. But then he would actually have to apologise for something for once in his life :v

Sasuke is already pretty destructive and full of violent thoughts so business as usual? Nah, as time goes by it will be noticeable that something is up with him even for those who know what he's like. As for the end of the plot he's have no issues with killing anyone that corrupted if it needed to be done!

I think I covered the basics if you wanna do anything in particular let me know!
