Per one of Niven's Laws ("There is no cause so right one cannot find [an evil person] following it"), there ought to be at least a few Mormons out there who are total jerks. I suspect that they keep them hidden away, though. ;)
There is a level of self selection taking place as the behaviours and characteristics generally held by practicing Mormons (Altruism, family/community focused behaviour, and the self control necessary to abstain from coffee, alcohol, sex.) are inversely correlated with those of 'Total jerks' (aggression, self centered behaviour and poor impulse control). So one would expect a low overlap between those two groups.

Having thought it over, I'm OK with the ethics of this service.
