Whomever you revive has all the capabilities their physical body can manage, but they never stopped decomposing after death and they are still decomposing. You could revive a skeleton, but they wouldn't do anything given that they have no flesh or brain, so it would just lay there being calcium. The injuries that killed them would still be present and they'd be in pain from the injury and decomposition, so there's that. Better hope they weren't embalmed.
