 As we shall see in Section 7, things may not be quite so simple. For, even if a group has the capacity to act if organized, there are other factors that need to be taken into consideration before we can posit a collective obligation and make a subsequent claim of collective responsibility. One of these considerations is whether the prevention of the particular case of harm in question ranks high on the list of the many cases of harm prevention that require the group’s attention in a situation where choices have to be made. Another is whether, given other demands on the group, including the well being of the group itself, it would be fair to expect the group to pursue this particular project (and hence take it on as a collective obligation).
