It doesn't because it's not the point, though. If it progressed further, it'd coerce V's final decision excessively. The point is to let even an outrageous fuckup of an Edgerunner who surrendered to Arasaka have a final epiphany and a chance to die with dignity, on their own terms. If V was even more fucked up, there would be little reason to not accept Arasaka's final offer. It'd undermine the thematics of the game, which center around rising above the filth, pain and delusions of a city built on cyclic suffering to achieve spiritual awakening and liberation. It was important to show it, but not muddle the point.
