Hateful injury to the person, or tear (9)
I believe the answer is:
abhorrent
'hateful' is the definition.
(I've seen this before)
'injury to the person or tear' is the wordplay.
'injury to the person' becomes 'ABH' (abbreviation for aggravated bodily harm).
'tear' becomes 'rent' (synonyms).
'abh'+'or'+'rent'='ABHORRENT'
(Other definitions for abhorrent that I've seen before include "far from agreeable" , "Hated" , "Repugnant, detestable" , "Detestable, loathsome" , "Repulsive" .)
