ZOMBIES! Curse or Infection?

cursed zombies tend to be overly arbitrary in how they work/spread/etc. and more often than not, the way the magic works, or where it comes from, is never addressed.
leaving the whole reason for zombies as "cuz we needed zombies"

also, involving a magic system means there should be an opposing force. so wtf? wheres the holy cleric turning undead on these things?

infections have basic rules everyone gets, and creates neat social situations.

what do you mean, where are they? When have you looked?
I'm going to laugh my fool pony head off the first time a big biker dude is rent to pieces, but the zombies are unable to enter an Irish bar because a guy got drunk and sanctified the place.

There probably already is such an opposing force, unobserved because has just never been opposed before. There could be constant unmeasurable energy that you don't see because it's opposite force doesn't show very often.
