No medic turned out to be evil (7)
I believe the answer is:
demonic
'be evil' is the definition.
(similar in meaning)
'no medic turned out' is the wordplay.
'turned out' is an anagram indicator (turn out can mean to organise).
'no'+'medic'='nomedic'
'nomedic' is an anagram of 'DEMONIC'.
'to' acts as a link.
(Other definitions for demonic that I've seen before include "Furious" , "diabolical" , "Wicked" , "Dime con (anag.)" , "Inspired as if by a fiend" .)
