But if we expand the scope a bit...
The Human Race was never the master of this world, has never been, is not now, and will not be in the future.
Among the Ten Thousand Clans, from ancient times to the present, they have been in a declining existence.
And the vast majority of races within the Ten Thousand Clans believe in the supremacy of individual power and the most primitive law of the jungle.
Therefore, each race within the Ten Thousand Clans actually hopes for different outcomes, and karma, needing to weigh all, cannot fulfill each race with one type of karma.
Unless the Ten Thousand Clans had each gone their separate ways from birth, not interfering with one another, but that is clearly impossible.
In fact, logically speaking, even though the previous realms no longer exist, with the authority in the hands of the King of Reincarnation, one could minimize one's tribulation.
