Morality is a set of rules that we come up with, and collectively enforce, to make our lives better. It is relevant to the goal of making human life better.
Choice is an illusion of subjective experience. An input is processed through a computing network via the laws of physics, and an output is produced. The brain itself has no power over the laws of physics. The processing structure is the result of genetics, life experience, and quantum randomness. So it is incidental. The laws of physics necessitate that each output be so. In the case of choice, once the information goes down the pipeline, a signal is sent between the unconscious and conscious part of the brain that a "choice" was made.
But no such thing could happen, because there is only the machine and the mechanics. And the latter shapes the former, and not the other way around.
