I would counter with morality is not religion. And religion is not morality.
The first tier of morality, as far as the moral operable software license is concerned, it is akin to Asimov's Laws of Robotics. Since robotics will most likely consist of a software component, the software itself should be covered by a license with morality clause.
I would then say the second tier is to not cause non-lethal suffering. This would include things like torture (physical), torture (mental), causing injury, disease and malnutrition.
The third and final tier would be socioeconomic suffering. It would not create artificially limiting factors when those factors are not a choice. (Sex, race, etc)
After that, there is plenty of potential for immoral software. The goal isn't to create perfectly moral software (hell it's hard enough to make software that work as intended regardless of morality) but it is to assure developers and users that the software will only be used to advance humanity in the broad sense.
