I can't help but think this kind of stuff is one of the most severe types of schemes there are. Not only is it the dishonesty of claiming to represent God, which is bad enough, but there's also the tricking people out of their money and the false hopes they give.
And then you have people who, because they believe that sending money to a televangelist will cure their cancer, wind up dying.
all of that is bad ENOUGH, but how many people have been turned against Christianity because they see this as an example of what it is? Maybe they've been fooled themselves. Maybe they see the shenanigans and conclude that all churches to this to some extent. (Especially in the "I don't believe in organized religion" crowd.)
