What if Sasuke's answer to Rikudou Sennin was...

[Mikasa Hagaromo]

Sasuke probably said something to likes of:

Hogoromo: Uchiha Sasuke, what is your answer?

Sasuke: ....I wan't to bring an end to this cycle of hatred. The hatred that took my clan from me...the hatred that took my brother from me. I wan't to see it to it's end with these eyes.

Spot on! You nailed Sasukes character to the tee.

 

[AGoodBoy]

Gaaayyyyyyyy

Glad this is the first response. This is spot on.

 

[KGB Kakuzu]

I can almost assure you it is not.

 

[chuloe]

He has been protecting nard's since he showed up in the war
That's probably why he didn't answer kakashi when he asked what was his true plan
He might absorb Nards like he did orochi haha
But seriously we all know sasuke is going to repeat the cycle entrusted by kaguya... it's inevitable

 

[Tennis Robot]

I hadn't thought too much about that. I would guess he either said "I want to make things right" or something about personal power.

 

[Kenshin the god of war]

I'll lose the little respect I have for sasuke if he had said that.
