If those church members, as here, received large sums of money from the pastor? Or supported him publicly? 100% yes.
I think it's especially obvious with churches. When a bunch of people get together to fund and empower a guy, they share responsibility for what is done with that power. If that power is used to harm, a factual accounting of who did what seems entirely fair, as does asking them what they have to say for themselves.
Your analogy isn't very good, though, because all of the people mentioned in this article are public figures. They sought out prominent roles in society. They receive significant benefits from the public, either directly or indirectly.
