>>3610337>Those monsters have been shown up to now to be just as flawed as human beings are. It didn't come out of nowhere, you're just a speedwatcher.Actually, the Angels have a simple goal in the show to support the monster of the week format (get to central dogma) and send increasingly complex iterations to try to reach it, starting with brute force and ending with infiltration by a human like-homonculous in Kaworu. The Angels also arguably coincide in the show with states of conciousness one might experience while meditating on the sephirot of the Tree of Life, from malkuth to chochma, with keter being the final two episodes, bringing the characters and the viewer through the initiatory journey from matter to spirit.
The monsters are about as abstract as you can get, both physically and metaphorically, including Kaworu, the physical embodiment of Chochma, which is divine masculinity or wisdom, as the first production of the divine hermaphroditic union of Keter (human instrumentality, all souls as one, etc.), going from Spirit to Matter. Basically Kaworu is associated with the state of mind Shinji needs to learn to be able to take masculine initiative, in order to join the hermaphroditic "all souls as one" union, and this culminates in the show with Shinji killing Kaworu to assure the survival of the human species.
The angels are about as geometric as you can get.
But only in the show. Anno apparently dropped the Kabbalistic framing in the rebuilds to tell a story that's more emotionally satisfying to him, and you get a Kaworu that's very different from what's in the show by way of Anno not writing according to alchemical formula.
