Anagram and synonym of "evil" (4)
I believe the answer is:
vile
'anagram and synonym of evil' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for vile that I've seen before include "Detestable" , "Very nasty, quite evil" , "___ Bodies, Evelyn Waugh's 1930 novel" , "Extremely unpleasant" , "Live (anag.)" .)
