The "I don't care about the world" attitude is troubling in another way. What point is there to saving Rei if no priority whatsoever is given to the world she must return to? This may anticipate what happens at the end, wherein Shinji -- upon retrieving Rei -- simply takes her in his arms and feels that all is well... despite (or, more likely, due to) being in the disembodied realm of the entry plug, cut off from all else.
Shinji has had trouble with the external world from the beginning, as explained through the hedgehog's dilemma. In fact, Shinji's external world up until halfway through 2.0 remains fairly limited, with him only interacting with Misato (mostly OK), Toji & Kensuke (good but superficial friends), Kaji (scary person), Asuka (to him, it's mostly sibling rivalry), and Rei. I'm not counting Mari. He hardly has any interest in others or interacting with them; the world outside his circle is utterly uninteresting to him.
So there are three concentric levels of Shinji's world:
1. Shinji's self or internal world - where his own consciousness resides and he is mostly lost with himself. Unit-01's entry plug should be seen as a part of this.
2. Shinji's social circle - the people he knows, interacts with and cares about (whether voluntarily or not).
3. The rest of the world - people he does not know, does not interact with and does not care about. This is the world Gendo, Fuyutsuki and SEELE deal with. And, up until now, also Kaworu.
Shinji arrived in Tokyo-3 with just level 1, his own self. He expanded that by piloting Unit-01, which became an extension himself. This also gave him a place in the social arena of Tokyo-3, which caused him to develop level 2. However, his social awareness does not extend to level 3 (yet).
Shinji's social circle (level 2) has been crumbling ever since Asuka was lost, causing him to withdraw from most of his other connections out of fear of being hurt again.
However, witnessing the loss of Rei drove him over the edge. In Shinji's point of view, Rei was one of the most important people in his level 2, and he was hurt greatly by witnessing her apparent death.
He reacted mostly instinctively, by doing the only thing he knows, and that is retreating back into himself (level 1), by piloting Unit-01.
And what does he do? He reaches outside of himself (and the core of his Evangelion) and pulls Rei back in. In other words, he takes a part of the world outside of him (Rei Ayanami) and includes this into his own self, his own consciousness, his own body (Unit-01's core and entry plug). Shinji explicitly withdraws from the world outside of himself, retreats back inside his own inner consciousness, and he takes Rei with him. In effect, he overidentifies with Rei to such an extent that he considers her to be a part of him.
This is a very Freudian metaphor for Shinji's retreat into immaturity, especially if you take into account all these allusions:
- Unit-01 holds the soul of Yui, his mother;
- The entry plug is a metaphor for the mother's womb;
- Rei is a clone or proxy for Yui, his mother;
- Rei is possibly connected to Lilith (or Adam), a thematical mother-figure for all of humanity - (WARNING: This is NGE-based argumentation seeping into Rebuild and therefore possibly incorrect.)
- Rei and Shinji form a mutual "mothering" relationship throughout Rebuild: on the one hand, Shinji feeds Rei, while on the other hand, Rei fiercely protects Shinji from Angels at her own expense.
One of Sigmund Freud's theories about the immature (newborn) child is that it overidentifies with the mother's nurturing, and considers the mother's body a part of itself. Weaning the infant from the mother and inducting it into the larger world is an inevitable part of growing up and becoming an adult, but requires great effort and inflicts great pain and suffering on the infant.
And this is exactly the opposite of what happens during Near-Third Impact. Shinji symbolically unbirths himself by retreating into his mother's womb (Unit-01's entry plug), forcefully claiming the personification of maternal nurture (Rei), drawing her back into himself (Unit-01's core).
And that is what Third Impact would also be: the unbirthing of humanity.
So why does Kaworu stop this?
One speculation is that Kaworu is the Freudian educator, who acts in Shinji's own interest by weaning him from his mother and forcing him to grow up, i.e. destroying Shinji's immediate happiness for his own good.
Another speculation (which I favor myself) is that Kaworu wants be the one to become unborn himself. This is especially poignant if you believe (like I do) that Kaworu has cold, self-destructive Lilith's soul in the Rebuild Universe, while it is Rei who has alien but strangely sympathetic Adam's soul.
However, this is speculation for another thread. Please do not discuss this Kaworu angle here, but elsewhere.
