Don't worry, I'm not loosing my mind. But whether you are Christian, Agnostic, Atheist, Thor-worshipper or otherwise, just pretend with me for a moment.
Armageddon comes and wipes out wicked people. There is a resurection and some kind of test and the ones that pass make it into the glorious new world.
How long would it last before a revolt? The history of the bible shows that even humans being blessed by God turn away from him en masse. Perfect, imperfect, even friggin ANGELS that are much closer and instructed directly by God (according to the book of Job) turned away. A whole 1/3 of them!!! Thats an awful lot!
So my question is, how long before all (or a significant number) of these perfect people in paradise revolt, and disobey what their creator tells them? How long before the whole world became "wicked" again?
