Opposed or perverse (8)
I believe the answer is:
contrary
I believe this is a double definition.
'opposed' is the first definition.
(thesaurus)
'perverse' is the second definition.
(I know that perverse can be written as contrary)
(Other definitions for contrary that I've seen before include "Carry out (command)" , "Quite like Mary" , "Opposite, perverse" , "At variance; awkward" , "Perverse, obstinate" .)
