When you are in the wilderness, or even lost and in a true life-or-death situation, do you consider faith a good thing, or a bad thing?
As a non-believer (I don't like to use the word "atheist" because people confuse lack of belief in god with belief that there is no god), I consider religious faith a bad thing because it is not based on reality. Whatever good comes from religion can, and should, be got without it.
