This paper reviews the four fundamental frameworks available in normative ethics to underpin the most suitable strategy to facilitate the design of synthetic morality in the context of Highly Automated Systems (HAS). Based on research findings, it will present an updated multidimensional-scalar system of levels of automation specifically adapted to Highly Automated Systems (HAS) in the context of Human-Human-Interaction (HHI). This framework integrates the variables of autonomy, accountability, reparation, actions, con- texts, access, and inferences to build and facilitate the design of synthetic morality on highly automated unsupervised systems form a consequential perspective. As part of this process, a form of calculation emerges to facilitate the calibration of moral computational reasoning in the context of HAS.
