Kindhearted (6)
I believe the answer is:
humane
'kindhearted' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for humane that I've seen before include "Inflicting minimal pain" , "Kind and sympathetic" , "Characterised by kindness" , "Benign - kind" , "Kind and merciful" .)
