So, probably Naruto will say this to Pain in reply;

-what is peace? do you know peace? you don't know what peace is.
-i know peace from people in Konoha
-i also know pain from akatsuki and orochimaru.
-i know both so i understand better
-you just know of pain, so your understanding is not complete
-i don't know what to do for now, but i know that pain does not create peace.
-i don't know what to do for now but i will not give up to find the solution
-you gave up on a noble effort and took the easy way out
-you betray your own cause
-you are wrong
-i'm going to prove you wrong

or something like that.
