Pragmatist condemned US hitman (8)
I believe the answer is:
humanist
'pragmatist' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for humanist that I've seen before include "eg Erasmus" , "Follower of non-religious philosophy based on liberal values" , "Pragmatist" , "Person putting homo sapiens first" , "Philanthropist" .)
