Her parents say they love her, but she has no real purpose, so they worked out a deal to keep her alive--which is somehow connected to the physical change in the Oracle. The fact that Sati has no purpose makes her especially vulnerable to deletion.

If Sati does not have a purpose as far as the Matrix is concerned, then how is her conception explained?

Obvious: she is a symbolic representation of LOVE and SACRIFICE. Her parents loved her so much they willingly betrayed (?) the Oracle to keep her from being anhilated/deleted as a program. They go so far as to accept a permanent separation from her in order to keep her alive. She will never see her parents again. Hence, the connection to sacrifice, but also selfishness...All that matters is Sati's safety, and so her parents betray the Oracle, but what does this mean? Does this betrayal hinder or speed along the events that Neo has to take part in? Is Sati's real purpose to weaken the Oracle?

If Sati's real purpose is to weaken the Oracle, then how is it possible that the Oracle does not prevent it from happening? She says in her final scenes that she was not sure of anything, thereby implying that her powers are limited in some way. Thus, if Sati is meant to weaken the Oracle, then how is it that the Oracle accepts her even after the preservation of Sati's existence has wrought significant changes on the Oracle?

Aesthetics and Sati:

The obvious first: clearly her ethnicity, whatever it may be, serves political reasons. The little girl that plays her looks Arab, (though I'm not really sure if she is, she looks Indian), thus connecting her to that tumultuous region of the world. Given the time period in which The Matrix trilogy was filmed, the reasons are fairly obvious>>>The Arab looking child (or Arab world) is undemonized and takes on the tender appearance of innocence, beauty, and wisdom. She is the object of affection for her parents, the Oracle, and even Neo. People fight over her. Who will win the right to protect and possess her? As far as wisdom is concerned, her statements to Neo are complex, and convey the sense that there is a hidden meaning.

Also significant is the fact that she is clearly female and a child. She is by no means to be seen as a threat, yet her existence has had damaging effects on the Oracle. As a child, she is also the perfect little victim. She is defenseless against all those entities that wish to destroy or possess her. However, I should mention here that while Agent Smith does find her, the audience never sees if he destroys her, transforms her, or merely keeps her out of the way until he can utilize her to his own advantage. Her simultaneous representation of Love deliciously complicates matters once it becomes clear that people within the Matrix wish to destroy her or possess her.

How is it that machines seek to win something as abstract as Love? She becomes the pawn in a game of power. Thus showing the audience that Love is something powerful--that it is something worth fighting for. All a person has to do is study the significance of male/female relationships with certain characters in the trilogy. Consider such relationships as: Neo and Trinity, Morpheus and Niobe, and Link and Zee. All concern characters willing to sacrifice their lives for the love they have for someone else. Love is also apparent in relationships that show admiration and affection between the male characters, i.e. Neo's loyalty to Morpheus, Morpheus' faith in Neo, the Kid's loyalty and admiration for Neo, Link's growing faith in Neo and Morpheus.
