so, if we want to be absolutely certain that robots are easy to control, even when we're not around, should we program them to obey religion?

well, it works when the elite do it to us.

but, i might worry we'd get more than we'd hope for - as the elite frequently have. 

if you're an aristocratic elitist, religion might look nice on paper as a tool to keep the masses in line with, but history is full of fairly violent blowback, and i might suggest the approach ought to actually be abandoned.
