 Perhaps this “clean-hands principle” can be generalized to explain why individual acts of ignorant, irrational, or malicious voting are wrong. The firing-squad example is somewhat analogous to voting in an election. Adding or subtracting a shooter to the firing squad makes no difference—the girl will die anyway. Similarly, with elections, individual votes make no difference. In both cases, the outcome is causally overdetermined. Still, the irresponsible voter is much like a person who volunteers to shoot in the firing squad. Her individual bad vote is of no consequence—just as an individual shot is of no consequence—but she is participating in a collectively harmful activity when she could easily keep her hands clean (J. Brennan 2011a, 68–94).
