Finish filled with wrath — is put at risk (10)
I believe the answer is:
endangered
'is put at risk' is the definition.
(to endanger is to put something at risk)
'finish filled with wrath' is the wordplay.
'finish' becomes 'end' (synonyms).
'filled with wrath' becomes 'angered' (wrath is anger).
'end'+'angered'='ENDANGERED'
(Other definitions for endangered that I've seen before include "in a perilous situation" , "Threatened" , "Like some species" , "put at risk" , "exposed to risk" .)
