Wild not evil? (7)

I believe the answer is:
violent
'wild' is the definition.
(synonyms)
'not evil?' is the wordplay.
'not evil' anagrams to 'VIOLENT'.
But, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for violent that I've seen before include "Using extreme physical force" , "Brutal - intense" , "Hot-headed" , "Tending to use intimidatory force" , "Bloody" .)
