That seems to compartmentalize morality, and limit free will to the 'soul'.
#Physics has nothing solid to say about free will or souls. We have yet to surmount the topic of #consciousness, or even life.
We can say the the #brain's internal structure changes over time, and stores past #information in an interconnected format. When faced with #decisions, the first filter or branch immediately draws from this data to inform the 'fight or flight' type response. The standard default is to back away from the unknown.
However, when you add more info to this data, you add more degrees of freedom. This manifests as '#FreeWill'.
