Miscreant, miserable person (6)
I believe the answer is:
wretch
I believe this clue is a double definition.
'miscreant' is the first definition.
(wretch is a kind of miscreant)
'miserable person' is the second definition.
(term for a unfortunate person)
(Other definitions for wretch that I've seen before include "Miserable fellow" , "Despicable person" , "Person in pitiful circumstances" , "Disreputable person" , "Someone to be pitied" .)
