'wicked impulse' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'men do havoc' is the wordplay.
'havoc' is an anagram indicator (I've seen this in other clues).
'men'+'do'='mendo'
'mendo' anagrammed gives 'DEMON'.

'that makes' is the link.

Can you help me to learn more?

(Other definitions for demon that I've seen before include "Fallen angel" , "Monster" , "beast" , "Wizard" , "Genius" .)

I've seen this clue in The Globe and Mail.
