Christians claim that evil can and ought to be requited with good. So in "Les Miserables", the Bishop inspired Jean Valjean to reform by telling the police that he willingly gave Jean the silver plate (and added the candlesticks) even though Jean stole the silver. Does this strategy ever work to reform an evildoer? Or is it merely a license to further evil? In some cases, might it be useful to "heap burning coals on [an evildoer's] head"? If so, when and why?
