So evil -- run out showing disgust (9)

I believe the answer is:

revulsion

'disgust' is the definition.
(revulsion is a kind of disgust)

'so evil run out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'so'+'evil'+'run'='soevilrun'
'soevilrun' anagrammed gives 'REVULSION'.

'showing' is the link.

(Another definition for revulsion that I've seen is " Disgust".)

I've seen this clue in The Telegraph.
