You talking about Kaworu here... or Shinji? I mean, you're trying to demonstrate that Kaworu is somehow different and therefore... stuff, but all you're doing is showing that he really isn't.
This might not be what you are doing, but exteriorly it looks like you are first assuming that Rei or Kaworu must be a certain way, and then you are selecting whatever qualities match up -- ignoring or downplaying whatever doesn't. This is cherry-picking, obviously. In any case, something is amiss when your self-imposed criteria for what FoK entities must be like are ones that none of the characters in the show satisfy based on an honest assessment of their behavior. You have to remember that humanity is a collective. Individual Lilin are weak and dumb; that's precisely why we band together in societies and pass on knowledge communally. Kaworu may have the soul of a god, but his body is a Lilin's and he has spent his life in that body living amidst Lilin. NGE isn't exactly subtle about the interplay between mind, body, and the Other. Adam's soul doesn't escape this unscathed.
Something this conversation is making me wonder is what the intended goal of Fruity speculation is. The Fruits are set up as a binary so that's how fans expect them to act, but NGE is not anywhere near this neat and pat. Any place there exists a binary, NGE is there blurring that binary, and this is no exception. The Fruits are an interesting metaphorical idea, but trying to turn them into something concrete with set rules (aside from "spiral energy organ that is in red ball sometimes") is a battle against the show itself. "You're all human. Why do you care so much about how everyone is different? What matters is how everyone is the same." A clean delineation is not something NGE remotely cares about. Every hammer you try using will have a bunch of nails resisting it. In this regard, Kaworu is basically hammersbane; his very existence is at the junction between worlds.
The Rebuilds even add to this by having him blue screen for over a minute the moment something doesn't fit his established knowledge because he lacks the ability to efficiently reason things out.
I'm not completely sure what "lacking the ability to efficiently reason things out" is supposed to mean; "he has Fruit of Life, therefore he no think so good"? "Blue screening" is something that people often do when they're in a stressful and/or high-stakes situation. Here it's used to provide "show don't tell" characterization. If I had to guess, I would first assume the intended takeaway to be something like demonstrating his hubris. Kaworu is a pint-sized god basically, and could have easily assumed Gendo was so completely under his pinky finger there was no possibility of the man doing anything treacherous. Not because Gendo didn't want to, but because how the hell would Kaworu not notice if he did? In any case, I'm fairly confident it's meant to be read as a moment of all-too-human weakness -- fitting for a scene where Kaworu "falls" from Alpha to Omega -- and not as some metaphysics lesson that only us geeks who wring every last drop of significance from secondary or tertiary story details will be able to find meaning in.
(A further complicating aspect of this is how Kaworu seems to get physically ill from the "falling" process, which stalls his ability to reach a conclusion since not many people can think clearly when they feel like crap, let alone when weird metaphysical shit is happening to them.)
meaning that a soul is essentially genetic information.
"Genetic" pertains to genes, which are chemical objects. Souls in Eva definitely are not chemical -- they're represented as little red lights, and are wholly metaphysical. "Hereditary" would be a better word.
(Re: Eva2, like any other supplemental source it shouldn't be used when it obviously conflicts with the show, as is the case with Seele becoming gods at everyone else's expense.)
