First of all I would like to give this chapter 5/5, due to its epicness and more importantly pace...Naruto is on a really important note and we will surely see epic fights in next few chapters. Now talking about Sasuke turning good, I believe that sasuke had changed a lot especially after meeting Itachi, so it is somewhat acceptable that, rather than going with emotions, he took his decision by knowing the facts. Now,talking about Oro turning good, then I don't think Oro had turned good, he is just pretending to be good and will strike later, so we will see Naruto-Sasuke fight later in the story...
