Turned on a bad parent (6)
I believe the answer is:
enrapt
'turned on' is the definition.
(I've seen this in another clue)
'a bad parent' is the wordplay.
'a bad' indicates an anagram.
'parent' anagrammed gives 'ENRAPT'.
(Other definitions for enrapt that I've seen before include "Spellbound" , "Turned on" , "state of ecstasy" , "Deeply absorbed in something" , "Fascinated" .)
