If God forced us to eternal happiness he would be a tyrant, and the happiness could not be real on our part, as no choice was involved. We could not feel real pleasure.
If God forced us to go to hell he would be a tyrant, and hell could not be real as no choice on our part was involved. We could not feel real pain.
If God forced us to have free will he would be a tyrant, and the free will could not be real on our part, as no choice was involved. We could not choose to choose.
It is right to equate God to a "force", as force itself contradicts itself under its own weight, much in the same manner actuality needs potentiality (passive).
Everything we understand of evil equates to an understanding of time, sickness is health which does not last, a broken relationship is lost agape or ero...death equates to a form of temporality in which everything we observe exists through limit as a form of relativistic negation where "it is then is no more". Hence our understand of eternal pain, is a continual recycling of the same old where limits are reestablished for what they are: time as a divisive sword and what existed once cannot extend past itself anymore.
Pleasure on the other hand can be view oppositely as a form of fruition past the original self into a new self. Hence eternal pleasure is continual growth without limit as a form of freedom in and of itself.
So in these respects, and from these very brief premises, our understanding of good and evil is an understanding of the nature of movement as a form of structure and ordering, equivalent to "being", in its very self. The problem again occurs is that time itself is a form of measurement, often times relativistic yet dependent on constants, and what we understand therefore is good and evil as forms of measurement in themselves in which being exists through the dimensions it stretches through and from.
The question occurs, considering everything we understand of God is through man (as prophets, mystics, saints, virtuous men/women, philosophers) what seperates God from Man entirely, if man is, as Heraclitus observes "the ultimate measurer"?
Christianity, where God exists as man,
Buddhism, where man becomes a god,
the ancient Mystery Schools of Egypt and Babylon, where man is fundamentally immortal through continual cycling,
Islam, where God demands man's obedience hence he looks down at man in turn raising man up like an ant to the eye level of the biologist,
native lore, where man becomes an extension of the earth yet the earth is the mother of man
atheism, where man exists as the extension of the universe through another cyclically progressive form of evolution
etc.
So what we understand as the problem of God, can imply the problem of man, hence the problem of "measurement"; therefore justice as reason through proportionality. In these terms, our understanding of good and evil is a problem of measurement through the premise we use: time. The problem of good and evil is a problem of movement, hence an understanding of ourselves as "space".
Some look to the density of matter as origin, while contradictorily looking to empty space for answers. The heavens, from which our ancestors measured reality, point fundamentally to the origin of good and evil as fundamentally a form of judgement where what was, is and will be is premised in the continual folding of space through itself. In these respects we understand ourselves through movement as a form of judgement, where judgement determines our nature.
The nature of judgement as an expression of the will, appears to be the boundary, which forms heaven and hell.
