I suppose if I was a general or something, the orders would become to capture the zombies and hold them in cells. However, in the case of a dangerous situation, violence would still be fully tolerated.
I really don't think Zombies can come back to life, tho. About 90% of their brains is permanently killed off when they zombify. "Curing" the zombies would simply shut down the virus, thus leaving them an empty shell. Either dead, or at least brain dead.
