Who is the forefigure of each

 In the news quite often the reason of someone being accused of some crime or some error, is that the accused does not have such fault, and someone picks him/her guessing that others then would copy her/him. But people do not copy the opposite end of tge spectrum, than what they themselves are. So if one wants people to learn away from their faults, one should have people halfway between the error and the average, or the average or like themselves, since such would serve as forefigures. Or tell of the grounds for such, and so would people themselves learn.
