Ill-used, warped, depraved (7)
I believe the answer is:
sullied
'depraved' is the definition.
'ill-used warped' is the wordplay.
'warped' is an anagram indicator.
'ill'+'used'='illused'
'illused' is an anagram of 'SULLIED'.
(Other definitions for sullied that I've seen before include "Defiled" , "Made dirty" , "Stained or blemished as reputation may be" , "Disgraced, being ill-used" .)
