Endgame Have Given Us A Much More Intimidating Captain America?

Would the MCU's Captain America losing his cool be uncharacteristic? Or is it what the character needs to feel more real after all the tragedy he saw? His anger is certainly justified, as he and everyone else lost half of the world post-"Avengers: Infinity War." Plus, it could have been interesting to see this unexplored side of him in the MCU. The closest he ever got to doing so may be on the helicarrier in "The Avengers" while arguing with Tony Stark (Robert Downey Jr.). But time and again, Steve Rogers' calm demeanor is why he often leads the Avengers to victory.

We know that Cap makes mistakes, which humanizes him a bit. He should have told Stark about Bucky (Sebastian Stan) and his involvement in his parents' murders, and he probably should have seen more of the corruption within S.H.I.E.L.D. long before they almost launched their endgame. Briefly losing his cool at Scott Lang seems to reveal the missing piece of his personality. The man has been through some of the worst things anyone alive has ever seen. He saw WWII with his own eyes. He lost his parents, his friend, and three-quarters of a century. However, how come we haven't seen his frustration play out? In any case, the passage in "Look Out for the Little Guy" gives us the opportunity to question if this version of Cap works.
