A troubled Ezra Pound's not one keeping body and soul together (6)

I believe the answer is:

azrael

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

'not one keeping body and soul together' is the definition.
I can't judge whether this defines the answer.

'a troubled ezra pound's' is the wordplay.
'troubled' is an anagram indicator.
'pound' becomes 'l'.
'ezra' is an anagram of 'zrae'.
'a'+'zrae'+'l'='AZRAEL'

Can you help me to learn more?

(Other definitions for azrael that I've seen before include "agent of death back" , "Angel of death" , "Islamic/Jewish angel; al Ezra (anag)" .)

I've seen this clue in The Independent.
