It just dawned on me that calling Legacy era Kevin "Grid Jesus" is accurate as hell. Not just in the sense of how he's seen in universe, but also in him trying to establish a "perfect" world that has an easily twisted meaning and wasn't very achievable to begin with. The obvious inspiration behind Clu 2.0's image and Occupation regime adored the concept of Passion Plays.
Add the "God making Adam in his image and then going 'now don't do anything bad ok?' Try to be sinless too'" analogy, and...yeah.
Which makes Kevin choosing Zen Buddhism as a coping mechanism that much more interesting, actually. (ok, not completely choosing it, because hey, he served up an entire pixel pig at supper. Maybe that doesn't count as meat?) I mean, it makes sense he'd want something that favors non-action and emphasizes the every day experience- he's trapped. One could argue he represents stagnation.
The reason I'll say "coping mechanism" is because...I'm not sure Kevin really gains from it. (What good is enlightenment in his position? What good would it do Quorra?) You can kind of see him still struggle with admitting he fucked up at the end when he tells Clu that perfection is "unknowable". A great, big word that defines something the mind can't grasp.
You know what the mind can grasp? When something doesn't exist. He doesn't tell Clu the goal was never real, that perfection is so goddamn subjective that it has no meaning. In a sense, Kevin's still clinging to his sense of higher wisdom/divinity; it's just been cloaked by eastern philosophy. His problem wasn't that he was thinking too big; it's that he wasn't thinking at all.
As a side note, remember how Annihilation changed one part of the book from "character isn't paying attention to her partner because she's too absorbed in something else" to "character is cheating" because they functioned as the same concept emotionally?
That's Kevin and the Grid. Hell, look at the way he'd sees others on the Grid. They're younger, fitter, more adoring and scantily clad versions of the people he knows, including himself. He's addicted to running away from the expectations/responsibility of real life, and it's no coincidence he got trapped in it after his wife died, which is exactly when his son would've needed him the most.
Point being, if Kevin had never got laser-zapped...this all still would've happened if he'd had a family. Just with less glow bikes and such.
