There is an automatic COURSE-CORRECTING MECHANISM (which is a combination of free-will and determinism) already in place:
The more selfless one is, the happier he becomes—as a result of which he gives what he has (JOY) to others and receives the same from others.
The more selfish one is, the more unhappy he becomes—as a result of which he gives what he has (PEACELESSNESS & PAIN) to others and receives the same from others.
Hence, God has neither apppointed “a faithful and discreet slave” to feed His people, nor will he appoint such an extraneous agency!
