true, but perhaps if we are created beings, could it be considered just a complication of the model? for example, consider a simulated universe like our own, where a being might get hit by a car. with AI evolved suffient enough, that AI would feel pain and perhaps suffer horrible injuries, even if the intention of creating the independent systems of automobile mechanics, and the laws of physics, and the evolution of the human nervous system wasn't to induce a state of suffering.

more specifically, on the biology of the nervous system, it's interesting how fear/pain/suffering itself was just a byproduct of natural selection meant to help us by telling our dumb humanoid ancestors the things we should avoid - things that cause physical damage to our flesh or our mental state, or make it harder to survive. so these things are meant to help us, or we wouldn't have evolved it at all.
