Wicked, if cruel -- is he? (7)

I believe the answer is:

lucifer

I'm a little stuck... Click here to teach me more about this clue!

'he?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.

'wicked if cruel' is the wordplay.
'wicked' indicates an anagram.
'if'+'cruel'='ifcruel'
'ifcruel' is an anagram of 'LUCIFER'.

'is' acts as a link.

Can you help me to learn more?

(Other definitions for lucifer that I've seen before include "Match - Satan" , "Morning star" , "Satan, the Devil" , "Rebellious angel; a match" , "striker" .)

I've seen this clue in The Telegraph.
