Nashikeine wrote he suddenly changed into a completely different character as the exams progressed He seems angry that the Leaf isn't shaping up to his expectations. He clearly experienced hardships, which gave him dive. The Leaf however suffers from lack of drive, as has been shown repeatedly. He even mentions that living under the protection of the 7th has left them weak.

He didn't change character though. He consistently wanted to prove he was the most powerful, something he maintains until the end.
