The fact they are building bunkers and shit I think they have some clue about what is coming.

15And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
16And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17For the great day of his wrath is come; and who shall be able to stand?

unfortunately they don't understand that only 100% surrender to him that sitteth on the throne will save them.
Probably because they're reprobates.
