For Sarah, the decision she needs to make is if they will continue this mission until Aiden gets his reward that comes with a position in the Voronin family or if they will leave this base and never look back (at least in terms of infiltration). But if they leave, it would be a waste of all the planning, and they will miss this golden opportunity to get into the system of the Voronin family undetected, and also… Sarah is not sure if Hong will be willing to abandon his revenge, probably not now when he got this close.
