Once upon a time, I've read quite interesting *yze of Sasuke's behaviour and psychological reasons behind his action. Let me leave a link here, because I strongly agree with it: https://www.reddit.com/r/Naruto/comments/3jvx3o/*yzing_the_psychological_reasons_behind/
Younger Sasuke put all hate and blame onto Itachi, planning to revenge on him etc. Later he turned it all againts Danzo and Konoha. You say his behaviour is like that of Naruto- but Naruto was never driven by will of revenge or hate- he was not trying to push everyone away and follow his goal like Sasuke, but was doing everything so people will notice him, to show them how much he's worth. While Sasuke's behaviour is sometimes questionable I wouldn't call it being like spoiled brat- he had set up a clear goal and followed only way he found right- "charging ahead"- because of isolation he was putting himself into, thinking that nobody can understand that- therefore, not listening to anyone. But it's all better said in that *ysis :victory:
