I don't disagree that they don't go looking for the oppurtunity I'm saying that it's a moral failure to go for it when the oppurtunity arisies. Being morally flawless in the absense of temptation is no challanging feat. Your morals are what is supposed to make you say NO.
I agree that succumbing to temptation is a moral failure. That being said, I don't think it has much to do with 'trust' and 'morals' as a lot of folks insist.
