Imagine, there is a social group, which I think is so evil they have to be banished or exterminated.
Freedom Party of Austria represents not fully exterminated Nazi scum and their sympathizers
The word I'm looking for should emphasize that I want the Nazis to be exterminated, and - sadly - many of them were not.
How do I say this in English?
In Russian we have the adjective недобитый (when someone was beaten, but not strong enough and/or was injured, but not killed). I'm looking for something similar in English.
