He's rough, tough, loveless and confused (4)
I believe the answer is:
thug
'he's rough' is the definition.
'thug' can be an answer for 'rough' (I've seen this before). I am not sure about the 'he's' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for thug that I've seen before include "violent gang member" , "undesirable character" , "Bully" , "Gorilla" , "violent man" .)
