The Architect: It is interesting reading your reactions. Your five predecessors were, by design, based on a similar predication: a contingent affirmation that was meant to create a profound attachment to the rest of your species, facilitating the function of the One. While the others experienced this in a general way, your experience is far more specific. Vis à vis: love. Neo: Trinity. The Architect: Apropos, she entered the Matrix to save your life at the cost of her own. Neo: No... The Architect: Which brings us at last to the moment of truth, wherein the fundamental flaw is ultimately expressed, and the Anomaly revealed as both beginning... and end.

The Architect tells Neo that an affinity for others was programmed in to assure self sacrifice. In Neo it's very strong.
