Putting a different spin on why there are humanoid races that sweep the good/evil axis and then there are races that seem to be mostly evil...
I was thinking that as part of a campaign world's mythos, these fallen races could have an origin in each of the seven deadly sins as defined in medieval Christianity, and perhaps some being characterized by the seven deadly poisons from Buddhism, and still others that violate specific major tenets of Islam, Confucianism, etc. These great religions need not be explicitly woven into the mythos itself, only that these vices or evil deeds appear as the major causes of the downfalls of these degenerate species.
Some suggestions-
Orcs: lust (being that there are more half-orcs than any other kind of hybrid short of maybe half-elves, this choice seemed quite appropriate)
Ogres: gluttony
Hobgoblins: wrath?
Goblins: sloth?
Kobolds: greed (they are related to dragons, after all)
How about the rest?
