i also thought that was a good analysis, but i would put the eldar as 'too alien to morally judge' - while there are a great many similarities between human and eldar, their emotional states surpass anything humans can experience, which is why they have the ridgidity of their 'paths'. we can understand that their emotions exceed our own but we can't comprehend how that would affect the evolution of their psyche.

"judge the morality of a people on how it treats it's enemies" i can't remember who said that, or the exact wording, but the gist is there. obviously this wasn't intended for use in a sci-fi multi-species galaxy, but all the same i think it has merit in this context. and the tau are the only ones who always attempt diplomacy, even with those they're at war with. and while their diplomatic overtures towards the tyranids were hilariously naive, it's the one thing that really endears them to me, they make the attempt.
