I came in late on this thread.
It is a good, and appropriate, moral dilemma for this group. You do not know what you will do until you face the situation. If you do not think through it, you may end up doing something totally wrong based on bad data.
Having served in some humanitarian aid situations where the people sere REALLY starving, the ones who survived were the ones with a strong sense of community, with leadership which pulled them together and made them work together to ensure that everyone was taken care of. The ones who were only looking out for themselves, or even just their family, did not improve their situation in spite of tons of food aid. Once the aid and security went away, they reverted to tearing each other apart.
I do not know what I would do other than ensure that my family survived. There are so many variables and too many different types of situations to say definitely what I would do. I have made hard decisions before, but I can't predict the future.
