That man will torture (4)
I believe the answer is:
hell
I believe this clue is a double definition.
'that man will' is the first definition.
('he'll', contraction of 'he will')
'torture' is the second definition.

(Other definitions for hell that I've seen before include "Satan's realm" , "Inferno" , "Devil's fiery home" , "Abode of the damned" , "Abode of evil spirits" .)
