Does Young Earth Creationism teach that Adam and Eve only had a concept of morality after the fall? Does Young Earth Creationism teach that Adam and Eve only had a concept of morality after the fall, once they had eaten from the tree of the knowledge of good and evil? 

If so, would they have been unaccountable for their actions before the fall?
Does Young Earth Creationism teach that Adam and Eve only had a concept of morality after the fall?

Young Earth Creationism is not often extended to such considerations.

One might assume that since a knowledge of good and evil was obtained after the infraction, the concept of morality was by definition more limited before the more extensive knowledge was acquired.

They did know morality in a more limited sense of knowing that they were not to eat the fruit of the tree.


  Genesis 3:2-3  And the woman said unto the serpent, We may eat of the
  fruit of the trees of the garden:   But of the fruit of the tree which
  is in the midst of the garden, God hath said, Ye shall not eat of it,
  neither shall ye touch it, lest ye die.
