Kane's control collapses as every ally abandons him — from 80 to 2 by the time Miller's train arrives. But his agency barely dips below 55. He CHOOSES to stay at every turn, CHOOSES to fight alone, CHOOSES to reject the badge afterward. The widening gap between the two lines — control falling while agency holds — is the film's thesis: moral courage is choosing to act when the situation gives you nothing.
