An athiest would be incapable of saying such a thing without betraying his atheism. As to "no longer in pain" who said anything about pain? What if the child just dropped dead or was hit by a car or drowned in a pool?
Logically with an attitude like that, the Atheist should be walking through hospital wards with a AK-47.
Exactly why would an athiest would be incapable of saying such a thing without betraying his atheism? Is being at peace impossible for them? As you must have read, I said ‘something like’, not anything specific. Why is it logical, that an atheist should be walking through a hospital with a weapon? That doesn’t make any sense at all.
