I think there's a bit of a difference with a lobster. If prepared properly the lobster goes to sleep before he dies. You put him in cool water and then turn on the eye. Doing it that way also ensures that the meat is tender.

Unlike how I did it because I didn't know any better. I was making a 'romantic' dinner for my wife and myself, threw the first lobster in hot water and cooked him up with his homey within watching distance. The second one, knowing what was coming... struggled. He wound up flipping himself over in the boiling pot and writhing in agony until dead.

That was the last time I bought live lobster. I've ordered it at Red Lobster, but they don't cook it in front of me.
