"Anyone who is found will be thrust through, and anyone who is captured will fall by the sword. 16 Their little ones also will be dashed to pieces before their eyes; Their houses will be plundered and their wives ravished," (Isaiah 13:15-16).
This is simply a prophecy about what will occur. It is a proclamation about the coming judgment of how Babylon will fall to the Medes. If someone comments about a coming war and then states that there will be children who will be destroyed, houses plundered, and wives raped, does it mean that the one who is saying it is approving of it? It just means that the unfortunate reality of war and its horrible consequences are easily known and even predicted.
