Wrong action - I'm for it, to my dismay (13)

I believe the answer is:

mortification

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

'my dismay' is the definition.
I can't tell whether this definition defines the answer.

'wrong action i'm for it' is the wordplay.
'wrong' indicates an anagram.
'action'+'im'+'for'+'it'='actionimforit'
'actionimforit' with letters rearranged gives 'MORTIFICATION'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for mortification that I've seen before include "Extreme embarrassment" , "Great embarrassment and shame" , "Chagrin" .)

I've seen this clue in The Globe and Mail.
