I doubt Mr. Ketch will become the reformed type, he's a psychopath and skilled torturer and the person he reminds me of is Alastair. Also, none of the previous psychopathic characters have been reformed.

He's likely to suffer a death at the hands of Sam, Dean, Castiel, or even a member of the British Men of Letters. If he does somehow reform, then I'll believe the writers have a weird sense of morality, which won't surprise me considering how a number of good characters have died...painfully.
