Unfortunately it's a dopy state that's as far from perfection as possible (8)
I believe the answer is:
dystopia
'state that's as far from perfection as possible' is the definition.
'unfortunately it's a dopy' is the wordplay.
'unfortunately' indicates an anagram.
'its'+'a'+'dopy'='itsadopy'
'itsadopy' with letters rearranged gives 'DYSTOPIA'.
(Other definitions for dystopia that I've seen before include "Undesirable place" , "Imaginary society in which everything is bad" , "worst possible place?" , "Imaginary place of maximum badness" , "there's no worse place" .)
