I agree.
The occasions where this has happened already, e.g. with Jeff Sessions, have produced very good results.
I wish in a way we could get a genie who would wipe out all our troubles, but this is not how God built the world. We got a Christ, not a genie. Progress from the worse towards the better will be possible. Flawless alabaster saints will never be possible till this mortal coil itself is out of the picture.
