What if when the accused gave the donation and the church carried out a thorough investigation on the source of his income; and the donation turned down? Those lives would not have been wasted.
The whole congregation/town cannot be ignorant of such donor's source of income if truly illegitimate.
We the society aided and abated this crime - from the villagers/laity who knew but chose to ignore, to the clergy who refused to ask questions, to our leaders who have chosen to celebrate any type of wealth and to our get rich any way or die trying kinsmen.
The society should start celebrating and promoting sincerity, hardwork and other chivalric codes.
