There have to be gods that oppose each other.
Lifetimes before one reaches the level of the lowest Daimon, there is already a point where opposition between the Gods is not only impossible, it is irrational.
Think of it like this:
Satya is Eternal Truth, and it is the Godhead.
Zeus is the mind and active agent of the Eternal Truth, and is himself Eternal Truth.
In order for even the Magnum Opus to be obtained, one has to be aligned with higher truths. These are synonymous with the Gods.
The Gods, the Daimon and Heroes all partake various levels of existence where there is no more death, but also no more duality, no more mayic notions, worlds inconceivable to us.
All Gods are fully on the same "team" and have the same goal, because this is also Zeus's goal, and the goal of life itself: creation of new Gods, perpetuation of life, victory of life over death and truth over falsehood.
This is a purpose They share in and partake in, not a "job" they uphold 9-5, then go home and go on gossip and petty disputes.
They are quite literally beyond these things.
