Made expiation at having done wrong (6)

Ross

I believe the answer is:

atoned

I'm a little stuck... Click here to teach me more about this clue!

'made expiation' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how they can define each other.

'at having done wrong' is the wordplay.
'having' means one lot of letters go next to another.
'wrong' indicates anagramming the letters.
'done' with letters rearranged gives 'oned'.
'at'+'oned'='ATONED'

Can you help me to learn more?

(Other definitions for atoned that I've seen before include "Made up for, say injury" , "Made amends" , "Expiated" , "Made reparation (for)" , "Made up for offence or sin" .)

I've seen this clue in the Evening Standard.
