Violent home, imperfect perhaps (7)
I believe the answer is:
intense
'violent' is the definition.
(similar in meaning)
'home imperfect perhaps' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'imperfect perhaps' becomes 'tense' (imperfect is a kind of tense).
'in'+'tense'='INTENSE'
(Other definitions for intense that I've seen before include "Strong in degree or emotion" , "Forceful, concentrated" , "Powerful" , "Extreme - strong" , "Teen sin (anag.)" .)
