I think most species have a bit of a social balancing act. They still need to basically take care of themselves first but they also have to have some concern for the welfare of others in their species. So as much as humans are social creatures, you're going to spend a month locked in a room with a stranger and there's only enough food for one of you, I think most people would put their own well being over his.
