  More personal leeway could also be allowed by deploying the legal notion of proximate causation. When a starving stranger would stay alive if and only if one contributed to a charity, contributing to the charity still need not be the proximate cause of the stranger’s life, and failing to contribute need not be the proximate cause of his or her death. Thus, if an act is morally right when it includes the most net good in its proximate consequences, then it might not be morally wrong either to contribute to the charity or to fail to do so. This potential position, as mentioned above, has not yet been developed, as far as I know.
