Exposed a crazy dude to a bad end (7)
I believe the answer is:
denuded
'exposed' is the definition.
(thesaurus)
'a crazy dude to a bad end' is the wordplay.
'a crazy' indicates anagramming the letters.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'a bad' is an anagram indicator.
'dude' with letters rearranged gives 'uded'.
'end' is an anagram of 'den'.
'uded' after 'den' is 'DENUDED'.
(Other definitions for denuded that I've seen before include "Stripped" , "Laid bare" .)
