Remember that the Vorlons existed in a unique dichotomy with the Shadows, that does not quite parallel other dichotomies that we’re familiar with.
Both were trying to achieve similar ends, the evolution of other species. And both were ruthless about achieving this, over the course of many thousands of years.
Philosophically, it could be said that the Vorlons were believers in the evolutionary theory of “punctuated equilibrium”, the idea that intelligent species are generally stable in their environment until something, in this case, the Vorlons, causes “Cladogenesis”, an orderly split into two species, caused by the introduction of, in this case, new ideas and technologies in a species separated by a distance.
So, they were in favor of “order”.
The Shadows, on the other hand, were firm believers in Natural Selection, that two intelligent species should be brought into conflict, so the better of the two would evolve, and the lesser of the two die out.
And since intelligent species cannot be counted on to naturally conflict with each other, the Shadows set themselves up to be the “nemesis”, at intervals, creating both animosity and alliances.
That is what made the series. That whole dichotomy and how it relates to reality. And perhaps some age old shadow societies on this planet. Actually did occasional work at the studio that did the Babylon 5 computer graphics, which was too notch back then. Had no idea what the show was about. Shame. They had some intelligent people working on it. Could of had some interesting conversations, no doubt.
