They have no idea what they are dealing with.

This stronghold controlling the planet, and injecting chaos, are being allowed to act out their intentions.

They don't realize that this is all a pre-written story, and the hammer will fall on them by the hand of God in due time.

They are being allowed to act out their intentions, because if they are stopped too early, they will deny their true intentions.

Just as if you arrest someone before they commit a crime, they will just deny that they would even do such a thing, therefore proclaiming their own innocence.

This is why this goes on.
