Did Huey ever particularly looked he would do great at Intrigue?
But if you step back and look at things, the 'whydunnit' was never answered about that mess. Miller said everything was his fault, but Miller is Angry. He wanted to blame someone and he took his anger on someone that did not lose everything like he did. So everything was seen in the worst possible light.
Hell, take the Sa... Whatever complicated name that giant robot was. He wanted to use his own child as test subject? He's insane, right? But take a step back: Because the cockpit was child-sized... No grown man can pilot it. Aka, someone that would have been far more competent with it. Like, say, Skull Face.
Just wanted to tone down the Huey hate, but it IS true we never got the why.
From my understanding the implication is that Huey is in fact...not as smart as he might claim he is. Remember that he basically stole Peace Walker's/ZEKE's design from what's-his-face in Russia and so on.
So you have this guy who ends up going through with these things and coming up short - which wouldn't be a problem
if he didn't start becoming full-on delusional. So now any mistakes he makes are either Working As Intended or Someone Else's Fault. The
real issue is that by the time of TPP Huey gets a bad habit of doubling-down on his bad ideas and denying any faults of his own which causes problems for
everyone.
Like with the Sahelanthropus piloting; the initial plan was to use another AI Pod, but he was shut down when it was pointed out that it wasn't really practical for the Soviets to build. But Huey is
never ever wrong, the small cockpit was
clearly planned to house a child pilot the whole time!
Obviously! Anyone who objects to that is
clearly wrong.
I figure that his initial betrayal was a mix of thinking that the Cipher soldiers wouldn't do anything
that bad along with just a bit of greed that he would later deny entirely.
He *still* shoved Strangelove inside the pod and not showing any remorse nor regret. But eh, that's just a footnote.
Also, as for Sahelanthropus, Skull Face is dumb. Just make Sahel bigger like 10-20% and you can fit a (relatively small) adult there.
He got it running with a creepy psychic child. Not his fault that Eli showed up with the hate complex to end them all, hijacking the aforementioned creepy psychic child.
Also it's pretty clear by the first time we see the two interact that Skull Face has realized that Huey is not the genius mech engineer he claimed to be.
