They probably dont care or mind

because
1.They believe they are saved, fair enough
2.They believe that it doesnt matter if everything is destroyed and everyone dies they arent because God is going to take them away, and bring them back when everything is mopped up and made nice and tidy. Minus everybody else. So they dont care .

Now is this the truth

I dont believe it is

I am still waiting for the adecuate scripture quote that endorses the rapture

It would be different if they though that all the suffering they think is of so absolutely necessary if you pleased happend to them , but they think they will be on some pink cloud blissfully unawares of it all
