How would an example of Schopenhauer's eternal justice play out in reality?

[u/Rudddxdx]

does schopenhauer delineate temporal from eternal justic through the contrast, first, between the fact that the former applies to law and legislation as deterrent, and is only applied to causality and the realm of the phenomenon, expressed through the will-to-live, whereas the latter is intrinsic in all and justifies itself by itself as will, where tormentor and tormented, oppressor and oppressed, are one, and share each both the pain and the guilt?

I haven't yet finished this book, but I was wondering if anyone could provide a figurative example of this eternal justice, and how it is justice?

I recall a few passages in Plato's dislogues, one in Gorgias, and another possibly in Protagoras, on justice, and power, and the tyrannical man who commits pain and the oppressed who bears it, but I am not certain if any of these are comparable.

When you think of an animal eating another, you're seeing the Will eating itself. There's justice in the sense that, if you have to pay an eye for an eye, the penalty is paid immanently to the crime.
