Rv17:15 'God put it into their hearts'

This may well be the start of it or may be a progressive feature, starting with plague, global economic devastation, the sequence of events is unspecified, any thoughts? In the present this is all speculation, roll your own dice?

"He said to me: “The waters that you saw, where the prostitute is sitting, mean peoples and crowds and nations and tongues. 16 And the ten horns that you saw and the wild beast, these will hate the prostitute and will make her devastated and naked, and they will eat up her flesh and completely burn her with fire. 17 For God put it into their hearts to carry out his thought, yes, to carry out their one thought by giving their kingdom to the wild beast, until the words of God will have been accomplished. 18 And the woman whom you saw means the great city that has a kingdom over the kings of the earth.” Rv17:15
