Wrath, for one (3)
I believe the answer is:
sin
'wrath for one' is the definition.
(I know that anger is a seven deadly sins)
This is all the clue.
(Other definitions for sin that I've seen before include "Go astray" , "Wicked deed" , "grave offence" , "'Transgression, mortal or venial (3)'" , "Fall from grace" .)
