Wishing to do what is right (13)
I believe the answer is:
conscientious
'wishing to do what is right' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for conscientious that I've seen before include "like some who object?" , "Wanting to do right" , "Taking great pains" , "Painstaking" , "Wishing to do what's right" .)
