Evolutionarily, you probably want those types too. An orderly tribe might get slaughtered by some unforeseen situation that they try to fight together; whereas the individualist "I don't give a shit" type might just run away - and let his genes survive. Same in situations of starvation: the DGAS types will lie and cheat to get a bit more of this and a bit more of that, ensuring the survival of their genepool - whereas the meek will probably die out.

Evolution is not a dinner party, to misquote a certain Chinese guy.
