Instilling love to rectify awful savagery (8)
I believe the answer is:
ferocity
'savagery' is the definition.
(I've seen this before)
'instilling love to rectify awful' is the wordplay.
I cannot quite understand how this works, but
'love' could be 'o' (love means zero in tennis) and 'o' is found within the answer.
an anagram of 'rectify' is 'fercity' which is within the left over letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ferocity that I've seen before include "Unrestrained and cruel savagery" , "Savagery, fierceness" , "Savage cruelty of temperament" , "Savageness" , "State of savagery and violence" .)
