As originally defined in the BOED, deathless were every bit as inherently good as undead are inherently evil. Of course, IMO, undead aren't inherently evil. And since it was Eberron that picked up the deathless and really made them work, and Eberron has murky alignments by definition, I don't really think it can be said anymore that deathless inherently equals good.
Demiurge out.
