Some unfortunate men deserve better (5)
I believe the answer is:
emend
'better' is the definition.
(emending is a kind of bettering)
'some unfortunate men deserve' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'EMEND' can be found hidden inside 'unfortunate men deserve'.
(Other definitions for emend that I've seen before include "change" , "Revise (a text) (E, not A)" , "Improve (writing)" , "Make improvements to (text)" , "Correct/revise (a text)" .)
