For what it's worth, this sort of thing is why I can't stand the religious claim that it doesn't matter if it's true because religion brings people comfort.
I'm generally not a big fan of the notion that big lies are fine if they give people solace, even if it were true that said lies actually did. But there's no real evidence that the big lie of religion gives that much comfort, on the whole. It's far more likely to give people irrational fears and make them think uncharitable things by suggesting that it's "god" that told them so. When I first read about how the choice to jump instead of stay in the WTC to burn to death became stigmatized, I didn't understand it at all. Why were people judging one choice over another in a choice-free situation? Then I realized the role that religious teachings about "suicide" played in the discourse, and, well, I'm too full of disgust to even respond with much beyond "fuck that noise".
