Enmity, hatred (6)
I believe the answer is:
malice
I believe this clue is a double definition.
'enmity' is the first definition.
(thesaurus)
'hatred' is the second definition.
(I know that malice is a type of malignity)
(Other definitions for malice that I've seen before include "'Ill-will, spite (6)'" , "evil intent" , "Hatred" , "Spite - desire to hurt" , "Spiteful, animosity, sometimes a forethought" .)
