To JWS it means that God can kill you anytime he sees fit.
Questions from Readers
What would happen to the one who chose to rebel after the final test when there is no death or Hades? At that time, Adamic death is no more. And Hades, the common grave of mankind with the hope of resurrection, is no more. Still, Jehovah can annihilate any rebel in the lake of fire, denying him any hope of a resurrection. That death would be like the death that Adam and Eve experienced, not the death that humans inherited from Adam.
However, we have no reason to expect any such outcome. Those who pass the final test will differ from Adam in one crucial sense. They will have been fully tested. We can be confident of the thoroughness of the final test because Jehovah knows how to examine people inside and out. We can rest assured that the final test will eliminate any who would misuse their freedom of choice. Thus, although it is possible for those who pass the final test to rebel against God and hence be destroyed, it is very unlikely that such a thing will occur.

Gawd ... how loathsome!
... and what does it even mean that "those who pass the final test will differ from Adam in one crucial sense. They will have been fully tested." Wasn't Adam fully tested, as well? - I just don't get it.
