Some clarifications:
1) It should hardly need to be said, but the option the Accursed prefers is Freedom. The text makes that abundantly clear.
2) In Freedom, The Apocryphal Curse is departing because Freedom is an interesting enough ending for the story of the Forebear and Hunger. But if Hunger did not relinquish Progression, it would not so depart. The former is the cause; the second is a necessary additional condition. Buying a ticket entitles you to ride the train, if you are also tall enough to ride.
3) From an expected-value standpoint, as best Hunger or anyone around him can tell, he most hastens the Victorious World by choosing Vengeance. Haeliel seems to be more in agreement with this than not. The Accursed, aside from what he's already said, keeps his own counsel.
4) If True Catherine is resurrected, they will get back together.
5) We can hardly imagine that the Forebear has a ~0.1-1% chance of becoming a High Cursebearer and yet Freedom Hunger would still struggle with Indenture, Tyranny and Decimation without the interference of the Apocryphal Curse. The latter three would be little more than a serious inconvenience to his like; if it comes down to it he can simply Cut Through.
