Not knowing right from wrong (6)
I believe the answer is:
amoral
'not knowing right from wrong' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for amoral that I've seen before include "Unconcerned with correctness" , "Without sense of right and wrong" , "Without moral standards or principles" , "without guiding principles" , "unconcerned about ethics" .)
