Well... all in all, paladin seems more locked to an oath than an allignment. You can chaotic neutral your way around town.
E.g. oath of devotion can use the rod to raise a certain husband as a zombie, oath of the ancients can't.
Oath of the ancients is explained well enough (protect the natural order. Zombie is not natural). Oath of devotion makes it sound like you're forced to play as lawful good. As long as you're not actively and acutely evil, though...
I guess this is what happens when we're not devoted to something solid for roleplay purposes? I really don't know.
