This rogue turned out honest (9)
I believe the answer is:
righteous
'honest' is the definition.
(thesaurus)
'this rogue turned out' is the wordplay.
'turned out' indicates anagramming the letters.
'this'+'rogue'='thisrogue'
'thisrogue' is an anagram of 'RIGHTEOUS'.
(Other definitions for righteous that I've seen before include "Morally justifiable, or people who behave thus" , "law-abiding" , "Just, upright" , "Moral - virtuous" , "Morally justified" .)
