And what is your justification for that? Do you have evidence that an organism that exhibits a defence reaction to a stimulus from being damaged actually experiences anything?
The word
damaged is the giveaway here, I'd have thought. As I said before, given that we can only ever have direct and immediate access to the moment-by-moment contents of our own consciousness and nothing else you can apply this every bit equally to other humans. Everybody bar psychopaths does so.
The fact that you - with what degree of seriousness it's impossible to ascertain - attempt to argue in such a barrel-bottom-scraping manner, flirting with denial of just about everything we know of anatomy and physiology as well as evolutionary biology, zoology, ethology and plenty more -ologies beside, always says to me that a truly prickly defensive reaction has kicked in because vested interests are at stake.
You don't consider it better. Maybe the pig would.
Given the way pigs are habitually treated on a scale that almost defies comprehension, I'd say that that seems unlikely in the extreme. Evidence easily found - or supplied, if you're going to be more than usually tiresome.
