A person would justifiably disipline a child as a consequence of their actions.
It would be unjust to punish a child as a consequence, that would be over-correction.
as a consequence of A & E action, God set them out on their own to learn disipline.
He didn't punish them with immediate death(on the spot) that would have been over-correction, and unjust. They were after all like innocent children(with sin)
