In the ages before the Rapture, men believed themselves to be the masters of the Universe. Thus they worshipped gods who catered to their hubris: gods who personally rewarded and punished them according to man-made codes of law. As such, in calamity every man stood alone, and in prosperity they fought viciously amongst themselves to receive a reward. A winner took all the acclaim, and a victim was burdened with responsibility for their own troubles.
Alas, the heavens do not work that way. Men are too small and too alike for them; the gods send both curses and blessings blindly. An evil man may escape unscatched, while his deeds bring demise to his whole village; a martyr may die thanklessly, leaving others to enjoy the blessings sent by the impressed gods. Thus, there will always be villains and heroes; and no society can survive if it scorns its men of virtue. So where is the justice in this? Only the Heavens really know if and how our souls will be judged in person, but there is no doubt that humanity is being judged as a whole.
