It also irritates me, since both Jack and Ten are so morally ambiguous, that they're the ones forgiving other people - I'd rather see other people forgiving them...
This fic does a beautiful job of addressing that issue - maybe not exactly in the way you mean, but I still think you'll like it. Jack-centric, written during S1 of TW and rather short:

Absolution. (He’s not sure what he’d like more, the chance to keep his anger or the chance to be forgiven himself.)
