Maybe somehow God will work it all out---they hope.
Or..........hopefully they (GB) are right about the resurrection and they will be brought back to life in Paradise without knowing they had been dead for (who knows how many) years. And if not, well........they're just dead and none of it will matter.

The greatest revenge is living a happy and successful life!
