Having interacted with him a few times online (if he was alive he would be on this comment thread right now, and would probably have been banned at this point) - he was severely mentally ill. I’m not sure if he had any form of political ideology that was coherent enough to be “theocratic.”
Like, when you run TempleOS, the majority of programs on there are about using random number generators to “talk to” God. There are keyboard shortcuts for this purpose. I don’t think he was fun to be around - I imagine that his parents were at the end of their rope by the time they kicked him out - but Davis spent the last ten years or so of his life completely untethered from reality.
It’s also got some somewhat overt Objectivist messaging? Syndrome’s line: “when everyone is super, no one will be.” is fascinating.
Like, you can make an argument that a major message of the film is that some people are born special and more capable than others, and should be alotted special privileges. Syndrome isn’t one of the golden few, and rather than accept that, he attempts to democratize super powers to some extent (although because he’s the bad guy, part of his plan is making money from this).
I love the film, I just get some odd vibes from it at times.
