ethical or vertical (7)
I believe the answer is:
upright
I believe this is a double definition.
'ethical' is the first definition.
(thesaurus)
'vertical' is the second definition.

(Other definitions for upright that I've seen before include "Pig hurt (anag) -- noble" , "with principle" , "Vertically honourable?" , "Key item" , "deserving respect" .)
