The main problem with this discussion is that some people cannot rid themselves of their real world reflexes. Yes, on our world, if you are forced to do evil, some could consider that you are not really doing evil since it was not done of your own free will. But honestly, first, it's not true, because the real world is not that absolute. I'm sorry to fall immediately into Godwin's Law, but please consider concentration camp guards. And that's all what I will say on the subject, since real world it not really the issue here, but it shows that there can be evil influences that push people towards evil, towards doing evil without relying on supernatural causes. note that this is not 'inherently evil", but shows that influence, subtle or not, can lead people to evil, to doing evil, to the "banality of evil" even without supernatural causes.
