In the first instance, the reaping of the angel represents:
a) the work of angels figuratively gathering sinners and tossing them into the wine press,
b) releasing the seven bowls of God’s wrath.
Note that it is through the release of the bowls that enrage men and motivate them
(Rev 16:9, 11, 14, 16, 21) to gather in one place to wage war (Rev 19:19)
In the second instance, it is Jesus Christ who figuratively “treads the wine press" and exercises God's judgment on mankind’s sin.
This results in the demise of all human beings. Note carefully that the beast and false prophet thrown immediately into the lake of
fire and were not judged before the Great White Throne (Rev 20:11-15).
