Of course not.
Don't say that Wang Gui in history never resented Yue Fei's punishment. He was forced to intimidate him because he was not brave enough, not a subjective betrayal.
1, according to the existing historical data, Wang Gui's role in the unjust case is that after Wang Jun falsely accused, he did not obstruct and suppress Wang Jun's declaration against Wang Jun's will, but submitted it. Therefore, Qin Gui, Zhang Jun and Wang Jun began to frame Zhang Xian, and then implicated Yue Yun and Yue Fei in the persecution procedure.
But in this process, Wang Gui was always reluctant, and had resisted Zhang Jun's coercion. Finally, the reason for submission is also because someone caught "private affairs" and was "forced to coerce".
So we can't say that Wang Gui betrayed Yue Fei subjectively.
3. When Zhang Jun mentioned to him that he had been punished twice by Yue Fei before, Wang Gui's attitude was clear: he didn't resent the two punishments at all, and clearly stated the truth of not resenting: he was also a manager and a general, knowing that if he resented the manager once, the general would not be a manager.
Therefore, not only is Wang Gui not a betrayal, but Yue Fei's behavior of maintaining military discipline is not the reason for Wang Gui's submission at all, and it is not that "the confidant can't stand the too strict mutiny".
4. The two times that Wang Gui was punished were not the two times in TV series at all. "Listening to Yue Fei's wife's disobedience led to almost being beheaded", especially a myth-this joke was recorded in historical materials, but out of careful Jidong wild talk, Wang Gui was never said to be unlucky. According to Wang Gui's position and reputation among Yue Fei's subordinates at that time, it can't be him.
