Where did I say that I, in this hypothetical, would leave immediately? If the whole point is that I’ve realized I’m damaging the firm with my actions, why uncharitably assume I would choose an exit path that exacerbated the damage I already caused?

The point is to make some sort of communication that you’re taking on board the consequences of your action, consequences that go well beyond trite platitudes of how difficult the process has been and how next time will be different.
