 Ross (2012: 87–89) wishes to avoid this implication.  MWSS  does not imply that at \(t_1\) Sally is obligated to kill exactly one person at \(t_5\) because whether Sally kills exactly one person at \(t_5\) causally depends upon her intentions at \(t_1\). So, Sally satisfies the following conditional by not satisfying the first part of the antecedent: (if whether Sally refrains from killing exactly one person at \(t_5\) does not causally depend on the intentions she will have after \(t_1\), and if all her maximally preferable, directly securable options involve killing exactly one person at \(t_5\), then she kills exactly one person at \(t_5)\). Instead, MWSS implies that at \(t_1\) (and at \(t_5)\) Sally is obligated not to kill anyone because she satisfies the following conditional only by satisfying its consequent: (if whether Sally kills no one at \(t_5\) does not causally depend on the intentions she will have after \(t_5\), and if all her maximally preferable, directly securable options involve not killing anyone at \(t_5\), then she kills no one at \(t_5)\).
