Primitive, brutal (8)
I believe the answer is:
barbaric
I believe this is a double definition.
'primitive' is the first definition.
(thesaurus)
'brutal' is the second definition.
(I've seen this before)
(Other definitions for barbaric that I've seen before include "Wild and savage" , "Uncivilized" , "Rabbi car for rough and uncivilised" , "Like 24 [BRUTE]" , "Cruel; primitive" .)
