>>96>that they are now the Adam and Eve
No true, when kaworu and rei are talking it's clear that there are people quitting instrumentality too - we just don't see them.
Shinji tried to choke asuka because, once he quit instrumentality, he falls into the machine of misunderstandings that drives the whole work: he's afraid and rejects (destrudo) her. Asuka, instead, caresses him (libido), showing affection, and then once again with her harsh words attacks him: this teaches that a person can be both gentle and cruel, that what she felt inside that was showed through that gentle touch it's not what she aftwrwards formulated in words - another example of the ambiguity and dualism of human relationships.
And no, Shinji is not relatable, he's an extremely characterized individual, just like asuka and rei. Everyone in that shows represent an extremization of human traits.
