It's not hypocritical to want to see the thing killed as humanely as possible.
What exactly is humanely? (I'll get back to this point) Do you know what is worse, to die by being slowly suffocated of oxygen, or thrown alive into hot oil? I imagine you have an opinion, but actually don't. They are both barbaric to happen to a human, correct? (It actually mean as humanly as possibly, or manner, the word, it doesn't mean delicate in nature, or less cruel)

And this is where humanly comes in further. We tend to look at things and consider if they were happening to us. But they aren't. This fish has no idea what is going on, it has no conscience. I could see if the fish was somehow lacking in nutritional value being cooked this way for entertainment...then I might say, well, that is stupid, why do that? But this isn't. It is the opposite. You're all just seeing what happens to your food. it dies, gets killed. I suspect it is everyone's deep-seeded shame working in overdrive here along with squeamishness, for if you like or ever ate fish and chips, you played a part as bad as these folks.
