Origen

Then again considering the benefit that would accrue to the whole world from His Passion, He says, But not as I will, but as thou wilt; i. e. If it be possible for all these benefits which shall result from My Passion to be procured without it, let it pass from Me, and both the world be saved, and the Jews not be condemned in putting Me to death. But if the salvation of many cannot be procured without the destruction of a few, saving Thy justice, let it not pass away. Scripture, in many places, speaks of passion as a cup that is drained; and it is drained by him, who in testimony suffers whatever is inflicted upon him. He sheds it, on the contrary, who denies in order to avoid suffering.
