Regarding the question of what philosophical view should be used, I wonder if it would also matter if someone were something like prioritarian rather than a total utilitarian. StrongMinds looks to focus on people who suffer more than typical members of these countries’ populations, whilst the lives saved by AMF would presumably cover more of the whole distribution of wellbeing. So a prioritarian may favour StrongMinds more, assuming the people helped are not substantially better off economically or in other ways. (Though, it could perhaps also be argued that the people who would die without AMF’s intervention are extremely badly off pre-intervention.)
