She briefly worries about the fate of any innocent bystanders but is comforted by the fact if the ADF's aim is off, any innocents will go to heaven. But she's so busy that she fails to remember that her assumption about heaven was an arbitrary one for her own comfort and shouldn't be used outside the confines of her own skull.

What your evidence for the fact that believers actually reason that way? There are Christians who believe that everyone who isn't a Christian will go to hell after he dies. If you were right those Christians would have less of a problem killing fellow Christians than killing Muslims.

In the real world things don't work that way. The belief works differently than you propose.

Josephine won't tell you that she makes her decision to bomb the village because she considers the average Afghan life to be worth a lot less than the average Austrialian life. She might not even admit it to herself.

What if the prospective change to the opposition caused her distress? Might she choose to believe that the government will almost certainly win the next election because that idea feels 'right for her'?

But change this CEO to a mother making a choice on matters of vaccines or faith healing, and now she hasn't made any kind of ethical lapse

There are very good reasons why the behavior of a CEO is more constrained than the behavior of a mother. A CEO gets passed very specific duties via a contract. He has to act according to what the societal consensus consideres to be right. A mother on the other hand has a lot more freedom to deviate from the consensus.

I don't see how the example of the CEO adds anything to your argument.

I don't think that this post will convince anyone who doesn't already share your own notion of what 'right' happens to mean. It doesn't really address any concerns of someone who has a different concept of what 'right' means.
