In Avengers: Endgame...
Black Widow kills herself on Vormir to obtain the Soul Stone.
The instructions from Red Skull to receive the Soul Stone are that you must sacrifice that which you love the most.
Hawkeye didn't sacrifice anything.
He actively tried to stop it...and failed. How is this death sufficient?
edit - It is not the same as this question since I am asking about getting the soul stone out of Vormir, specifically in how they did it in Endgame. Not transferring it once it's been removed from Vormir
