[Matrix] What did Smith want? What was his purpose?

Why did he try to kill neo, destroy Zion and take over the entire matrix? What did he want?

He was programmed to act as a nemesis to mankind in general and Zion in particular. To not just fight them, not just hate them, but to hate their very means of existence; the very act of living in a human world with human sensations was repugnant to him. This hatred drove him in his assigned task, to seek and destroy Zion's operatives at all possible turns. This hatred and disgust was already pushing him to the edges of his programmed task during the first film, plotting to destroy Zion entirely.

But that's not his purpose. His purpose was to make the Zion crews feel enough pressure to not do anything too overt, but not enough pressure to die out entirely. By design, *Smith can never do what he was programmed to do*. He and his fellow agents were set up to fail from the very beginning, pawns in the Architect's design to keep the cycle going. And when the One emerges they are called home.

But before Smith could get called home, he went through his traumatic death and rebirth at Neo's hands. He came back still hating humanity, and hating Neo as well, but no longer with any compulsion to defend the system or secure the Matrix. He could go full tilt against Neo, and happily take the whole system and every human in it down in the process.
