Clean hands OR a pure heart?

Give people a chance to cleanse themselves after reminding them of some immoral action, and you reduce their altruistic drive. Score one for the Protestant side in the controversy over auricular confession. But what about the tendency to do something else that’s bad?

Apparently hand-washing substitutes for altruistic action in soothing the pangs of guilt. That would seem to weigh on the Protestant side of the debate over auricular confession. But I’d like to see someone do the other half of the experiment: presented with a minor temptation, are those who have cleansed themselves more or less likely to take it? My bet would be on “less likely.”
