Who boasts a disturbed heart? (6)

I believe the answer is:

sadist

(Other definitions for sadist that I've seen before include "One who takes delight in cruelty" , "One taking pleasure in cruelty" , "One who enjoys making others suffer" , "Cruel type" , "One enjoying hurting others" .)

I've seen this clue in The Sun.
