On shadow of the colossus how do you beat the very end of the game after you have defeated the last colossus

Unfortunately, there's no way to beat the VERY end of the game because you are not actually meant to. But, when the soldier stabs you in the chest and then the Priest throws the sword into the pool in the center of the tower, you could try to hide behind the pillar of each colossus. Try to repeat this until you are out of its reach to then get to his dead girlfriend. Technically, the only reason you get control of the character to show his frustration and the fact that no matter what you do, you cannot keep it from happening... you will fail.
