I'd have the same reluctance to say out loud, "May X, a person I love, be killed today in a car accident!"
But for Hutson and others who are perplexed at the dogged persistence of “magical thinking,” it gets worse. Hutson cites studies that show the persistent belief in God is not merely understood as some distant Deistic First Cause but, rather, of a God who cares, a God who judges and a God who might punish. Deep in our bones we are intrinsically theistic. He writes, “Even atheists seem to fear a higher power. A study published last year found that self-identified nonbelievers began to sweat when reading aloud sentences asking God to do terrible things (‘I dare God to make my parents drown’). Not only that, they stressed out just as much as believers did.”
Why Atheists Don’t Really Exist
It seems it is hard to escape the primal feeling that there is something out there we'd rather not **** off.
So I'd be more interested in the report if a non-God test was run parallel to the God test, so we could compare results.
In other words, it seems to me that the problem is with the sentiment itself, regardless of the intended killer.
