Not everyone is dedicated to the whole species.
It is perfectly possible to be fragmented, to have loyalties that are tribal. In the urban areas, gangs fight one another. This is serious stuff, this is tribal fighting.
Much of history reflects this struggle of tribe against tribe.
Then we can say "nation." In the mid-East, the "Arab League" condemns Assad of Syria, but these members are hardly united on any one principle, so, instead of a unified intervention in Syrian affairs, it is one in which each has their own reason.
Where there is no higher principle, one is simply loyal to one's own tribe.
