Softhearted (6)
I believe the answer is:
gentle
'softhearted' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gentle that I've seen before include "Mild; a maggot" , "Not stern, coarse or violent" , "Moderate in effect" , "Mild and benign" , "Mild and considerate" .)
