'Characters in Macbeth conform to gender norms.' To what extent would you agree with this statement?

Initially, Macbeth is described as 'brave' and 'valiant' by his fellow comrades. These men speak about Macbeth attacking someone on the battlefield, he "unseam'd" his opponent "from the nave to the chaps." The wording of "unseam'd" offers a godlike action performed by Macbeth. The employment of colloquials "from the nave to the chaps" offers a distinct view of the killing, as though it was effortless for 'brave' Macbeth, as well as offering light undertones. This displays Macbeth to be conforming to gender norms as he lives up to the expectations set by his sex. Within the early 17th Century, men were expected to be exceptionally masculine and violent, showing no emotion. In a recent portrayal of Macbeth on the stage he had a thick Scottish accent and wore bloodied armour during this scene to portray his rugged masculinity.
However, observing Macbeth in the latter half of the play, the audience can view Macbeth's unraveling sanity, and with that comes his lack of consistency in masculine traits. Macbeth is frightened by the sight of Banquo's ghost. Lady Macbeth asks him the rhetorical question, "Are you a man?" Macbeth issuing the slightest bit of emotion put his masculinity on the line, as the emotion of fear was most associated with femininity in the 17th Century. Macbeth attempts to compensate by telling the ghost that he cannot be frightened, he compares himself to many animals, one being a 'rugged Russian bear' bears have connotations with being ferocious. Additionally, the alliteration creates an 'r' sound, which sounds like a roar, in this instance Macbeth is trying to snatch his masculinity back by overcompensating. Therefore, I agree to an extent that Macbeth attempts to conform to this idea of gender norms, but naturally he has emotions and feelings that he has been forced to hide in order to appear masculine and deserving of the crown.
