Why did Captain Marvel not use the Infinity Gauntlet instead of Iron Man?

The record-breaking blockbuster hit film Avengers: Endgame had left quite a few Marvel buffs teary-eyed but some walked out feeling a bit confused. 

Many fans had wondered why Tony Stark aka Iron Man had to be the one to sacrifice his life, given his strength had already been hit following an extensive and tedious battle with Thanos and the army.

Fans pointed out to the scene where Captain Marvel, hailed as one of the strongest Avengers, (clearly, as we see her single-handedly destroy a massive spaceship of Thanos’ army) was seen protecting the Infinity Gauntlet and running with it to pass it on to Iron Man.

What a lot of us did not understand was why Carol Danvers herself could not have worn the Gauntlet to destroy the army, being the mightiest of all.

The director of the record-breaking blockbuster hit, Joe Russo, came aboard and cleared the confusion: "Captain Marvel can also withstand all the power of Infinity Stones at once. The reason we choose to let Iron Man do it, in the end, was that he was the closest one to Thanos at the time."

However, another theory explains the muddle a bit differently, claiming it had been because of Hulk’s reverse snap which made the Gauntlet unfit to be worn by anyone else. No one was given the opportunity to wield the stones – but how did Stark do it?

Thanos had answered that question in the film: “The hardest decisions require the strongest wills.”
