The intuition that machines cannot be as ethical as humans is likely incorrect. Ethics is the systematic resolution of conflicts of interest under conditions of shared purpose. Ethics is not irrational. There is no reason to assume that machines cannot be more ethical than us.
Affective states (like fear) are configurations of cognition. But they are not necessary for ethics and cooperation. For ethics, the right set of preferences and reason are sufficient.
