from wikipedia
After losing Yui, Gendo left Shinji with a teacher when he was a
toddler so he could focus on "Project Evangelion." This abandonment
has caused Shinji to have little to no self-esteem and to become very
reclusive and avoidant of difficult or painful situations, using
escape as a shield. He is often shown listening to his SDAT player
with headphones, blocking out the world. He appears in some ways to
be the opposite of the extroverted Asuka, though not as much as Rei
does. He also is shy, timid, and afraid of physical contact,
especially from the women around him. Asuka tries to get Shinji to
assert himself and even gets him to admit that he tried to kiss her
when she was sleeping. In episode 15, Shinji kisses Asuka, at Asuka's
insistence; Asuka pinched Shinji's nose so he wouldn't breathe on her
and tickle her face, nearly suffocating him. In the original episode,
Asuka washed her mouth out thoroughly afterwards; however, the
director's cut shows that this was an act, and that the kiss and
Shinji's reaction (or lack thereof) mattered a great deal more to
Asuka than she let on. Shinji is also somewhat intimidated by Misato
(who seems to enjoy teasing him good-naturedly), although her drunken
behaviors and slobby housekeeping habits irritate him.

Shinji's relationship with his Evangelion and status as a pilot is
very ambivalent. On the one hand, as an Eva pilot, Shinji is very
reluctant to go to war, to cause deaths, and to enter battle or to
actively do things; on the other hand, he is given strength by his
mother (whose soul is contained in Unit 01) and he defines his self
by piloting the Eva. Sometimes Unit 01 reaches "berserker" mode - a
state in which the Eva is activated without an apparent energy source
- helping Shinji in his times of need. During the battle with the
Angel Zeruel, Shinji exceeded a 400% sync ratio; he was able to
defeat the Angel but was physically absorbed within the Eva, where he
briefly met his mother.
Shinji's estrangement from his father and his mother literally being
inside Unit 01 is believed by some to represent the Freudian Oedipus
complex. His apparent attraction to Rei, who is a partial clone of
Shinji's mother and Lilith, could also be seen as proof of this
psychological aspect of Shinji's character; however, his attempts to
gain Gendo's acceptance and love and his attraction to Asuka could be
seen by some to counteract this idea. He may also be seen as suffering
from the culture-specific psychological disorder taijin kyofusho and,
from a Western psychological perspective, generalized social phobia
(and developing avoidant personality disorder).[citation needed]

While he is acknowledged later in the series to be a skilled Eva
pilot, he is never really shown to have any other notable skills, in
contrast to the other children (Toji is athletic, Kensuke has immense
knowledge of everything associated with the military, and Asuka is a
14-year old college graduate). It is revealed in episode 15 that he
is a cellist, something of which he had made no mention previously in
the series. Thereon, the cello appears as a recurring motif in the
series, possibly representing Shinji's "identity" - indeed, his
musical talent seems to be the only way in which he feels that he can
openly express himself. He claims to be untalented, but is shown both
in episode 15 and in Death and Rebirth playing Bach's Cello Suite No.
1, a fairly difficult piece.[citation needed]

Shinji has often been seen as a version or reflection of the creator
of Evangelion:

Shinji does reflect my character, both the conscious and unconscious
parts," Anno admits. As a pilot of Earth's most advanced weapon,
Shinji is far from the archetypical hero. Abandoned by his father
Gendo at a young age, he eschews human contact so that he cannot hurt
others, or in turn be hurt by them. The comparison, however, isn't to
be taken too literally.
"I wasn't thrown out by my father or anything" he laughs.
Nevertheless, Anno has referred to the plotline as a metaphor of his
life.
