Balance vs Good

When judged at the court of the Mighty Osiris, your 'jeb' (heart soul) is placed on a scale against the feather of Maat, the goddess of justice, morality, and religion. If the heart was found to be heavier than Maat's feather your soul will be given a second and permanent death. On the other hand, if your soul is found to be in balance with goodness, justice and truth, it will be given eternal life (at least in theory, since there are plenty of perils in the afterlife).

What I find interesting is the fact that the considerations given here are either to a balanced heart or a guilty heart; but what happens to the heart that is lighter than the feather, tipping the scale in the opposite direction? Is it impossible to fathom a heart that is purer than the epitome of purity? The balance methodology is being used by the gods (the curiosity persists as a metaphor, since there are plenty of other obvious alternatives), so it must occur to all the gods assembled that it could definitely go the other way. What happens then? I am yet to encounter a spell that addresses this possibility but it would probably involve pulling down the initiate down to 'earth'.

It is key to understand also that the entire transaction does permit trickery, since the initiate is allowed to utilize the scarab amulet to silence his heart from betraying his secrets and past sins at his tribunal, albeit giving enough information to make sure the scale balances out accordingly. But again...what happens if the initiate decides to conceal too much and tilts the scale in the complete opposite direction?

Balance, it seems, is a higher value than good. It also seems to be key to the magical art of concealment and misdirection.

Nonetheless, the very notion that things could be unbalanced in the favor of righteousness is apparently too crazy of an idea to take seriously by those who journey to the land of the dead.
