To live, to judge, and to scold (6)
I believe the answer is:
berate
'to scold' is the definition.
(synonyms)
'to live to judge' is the wordplay.
'to live' becomes 'be' (synonyms).
'to judge' becomes 'rate' (rating is a kind of judging).
'be'+'rate'='BERATE'
'and' is the link.
(Other definitions for berate that I've seen before include "Rebate (anag.)" , "Carpet" , "Censure severely or angrily" , "slate" , "Scold harshly" .)
