Well, I can definitely see how it would disgust or repel some people, but, really, it's a cultural thing. I had it in Korea - on a very chilly night in Seoul with some Soju (Korean vodka) - and loved it. Perhaps you already know this, but, the animal is, in fact, dead, the moving tentacles remnants of nerve endings that have yet to die. The octopus is killed very quickly, and probably suffers as much or less than a lobster being thrown into a vat of boiling water and definitely less so than a great many cooped-up chickens. Then again, we can't really know this for sure, can we?
Barbaric? Maybe so. But no more or less than eating other animals that have been killed for our dining pleasure.
