It's ended badly as foredoomed (8)
I believe the answer is:
destined
'foredoomed' is the definition.
(thesaurus)
'it's ended badly' is the wordplay.
'badly' indicates an anagram.
'its'+'ended'='itsended'
'itsended' with letters rearranged gives 'DESTINED'.
'as' is the link.
(Other definitions for destined that I've seen before include "Didn't see, being fated" , "Designated" , "Fated, fore-ordained" , "Intended; doomed" , "Intended (for a particular end)" .)
