The Architect created the first Matrix as a utopia for the humans whose minds inhabited it. However, the human minds rejected this first attempt as a perfect world and beta 1 of the Matrix crashed. A second attempt added "vulgarities" of human nature and a basic cause and effect, but this beta was also a failure. The Architect turned to a more intuitive program designed to understand human nature and psychology to augment the framework of the next Matrix. This time, the power of choice was added to the programming, where humans would be allowed the power to choose, even if the person was only aware of the choice on a vague, subconscious level.
