I believe the answer is:
neglects
'doesn't care for rebellious general celts butchered' is the definition.
I can't judge whether this definition defines the answer.
'rebellious general celts butchered' is the wordplay.
'rebellious' is a reversal indicator.
'general' becomes 'gen'.
'butchered' indicates an anagram (I've seen this in other clues).
'gen' in reverse letter order is 'neg'.
'celts' is an anagram of 'lects'.
'neg'+'lects'='NEGLECTS'
(Other definitions for neglects that I've seen before include "Fails to attend to" , "Leaves untended, fails to take proper care of" , "Disregards, leaves unattended" , "Ignores or overlooks" , "Fails to pay proper attention to" .)
