Ashi,
You remind me of a good point...supposedly, the Flood was to destroy wicked humans. God 'regretted that he made man', but after the deluge vowed never to do it again. But...who was really responsible for the badness?
It was the fallen angels. Their offspring raped, stole, and otherwise oppressed humans. Of course the fallen angels were at liberty to take up their wings and fly away on the ether.
What utter nonsense... Well, actually, it's quite good if you treat it as a mythological story. But to propose the Flood as the model for a future destruction is madness! (Note: I am not calling Jesus a liar...just a bit misinformed. He must have been sleeping through his prehuman existence not to notice there was NO flood)
What makes JWs think that Satan and his fallen angels won't avert destruction again? (That's intended to be purely rhetorical...but JWs, feel free to muck it up if you wish.)
