Rate me late, took too long getting this down.
I hate 'religious leaders' like that so, so much. Finding their weaknesses, exploiting them, preying on people's beliefs like that.... I hate it. Keep in mind you'll see these sort of people in all sorts of situations where money has the chance to exchange hands too (crypto, get rich quick scams, 'charities').
It's not necessarily on a grand scale also. It can be as simple as a relative being taken advantage of by a friend or family member. One of mine had a caretaker spending his money on Publisher Clearing House sweepstakes, theft and gambling pretty much; it was a horrible experience for my family. I heard about something less criminal involving my sister's mother-in-law, but still people being scummy taking advantage of family (and stubborn generosity; but then my BIL was being hit up by said MIL for money... Old lady was starving herself pretty much). If you know anyone susceptible, keep an eye out.
