from his point of view - why should he? no-one from his own species could comprehend the scale of his intellect. this includes the primarchs, which he created as tools for his own use, and you wouldn't expect your hammer to question your motivations when you're putting up shelves would you? (it's maybe a lame analogy but you get the point)

about the omega vault - all that is known about it is that it was built by humans - really? isn't it actually just assumed that it was built by humans, because of the human-friendly virus? i will point out though that all i know of the vault is from its page on this wiki.

personally i do think humans built it (dark age of technology, probably), but maybe it's a creation of tzeentch. he has a (far) greater understanding of possible futures than the emperor ever did so maybe the vault is counting down to some apocalyptic design or the possible enslavement of the entire human race.
