Xel'Naga Plot Analysis

[ragnarok]

Well, the Overmind's successful invasion of Aiur would have had one of two outcomes: 1.) Without the Khala, the Protoss would have fallen prey to the Swarm, assimilated, and destroyed; or 2.) With the Khala, the Protoss would have resisted, and be destroyed.

Thus Amon achieved his aims of destroying the Protoss, while a third party (Duran) artificially combined the two of them to create the Hybrids.

You have to remember the Khala is exactly the reason why the Overmind had to seek the Khaydarin crystals as a way to allow the swarm to bypass it and continue the assimilation process. This makes me really wonder about the crystals and if they have been left by the regular Xel'Naga or not, and something Amon didn't take into account

Inconsistencies: Why did Amon make Protoss immune to the hyperevolutionary virus and infestation if he had originally intended to combine the protoss and zerg?

You got the question the wrong way round. Amon couldn't have given the Protoss immunity to something it hadn't seen or developed yet (Zerg). It should be why Amon didn't give the Zerg the ability to assimilate Protoss knowing that it wanted to create Hybrids and that he gave the Protoss the Khala (or whatever the excuse is that gives Protoss immunity to Zerg assimilation)? Stupid is as stupid does, I suppose.

He didn't give the Protoss the Khala, the Khala existed before he even went to Aiur. It's more like when Khas rediscovered the link in the Aiur Caverns, the Khala changed, but Amon didn't know this change would prevent Zerg infestation/assimilation (at least without work on the Khaydarin crystals)
