Criminally divert pay — such wickedness (9)
I believe the answer is:
depravity
'wickedness' is the definition.
(thesaurus)
'criminally divert pay' is the wordplay.
'criminally' indicates anagramming the letters.
'divert'+'pay'='divertpay'
'divertpay' anagrammed gives 'DEPRAVITY'.
'such' is the link.
(Other definitions for depravity that I've seen before include "Moral corruption" , "Moral turpitude" , "Immoral act(s) - wickedness" .)
