Whoa, why are you using such an incredibly complex example, complete with multiple unstated assumptions (e.g. that the person who has the belief also believes that the Bible's requirements should be heeded--clearly not true of atheists, for example) and substantial authoritative support (albeit ultimately inadequate), making the task far from trivial.

It's much better to use a simple case like the belief that 5G wireless causes covid symptoms (including death), and covid vaccines are actually microchips used to control or at least track you.

If 5G wireless is killing many people, you have a moral obligation to try to save people, if necessary by destroying the equipment that's killing them. You also, however, have the moral obligation to not let this kind of utterly unsupported and physically impossible garbage into your head.
