1) Ghouls have no known age limit. Several Ghouls alive today are among the first that came to be.
2) Some ghouls are still intelligent.
3) Ghouls seem to be fully capable in all important areas of function.
4) People have pursued dumber goals.
5) They're ugly. But let's face it, after 200 years, humans get far uglier.
6) They're healed by radiation.
7) You can save money on haircuts.
But between Fallout 3 and New Vegas (I don't recall any in Fallout 1, but my memory is fuzzy on that game) there's only one cult of people trying to be ghouls. And they can be talked out of it. Talked out of immortality. The only way you could talk me out of pursuing immortality is at the barrel of a gun.
Gimme some of that ghoulification.
