Precisely the same as was the agony of the first Adam in the garden:
Willful separation from God aka death. A self-sacrificial decision made of his own free will to save his bride.
This decision was made by the first perfect man, Adam who took full responsibility for the sin of his wife Eve.
And the same decision was made by the perfect God-man Jesus Christ Who took full responsibility for the sins of His wife the Church and His divorced wife Israel.
Adam, however did not have the power to save all of his seed by his sacrifice.
But the infinite God Jesus Christ, by the power of His infinitely potent sacrifice......does.
