"It’s a good thing that bugs aren’t sentient then right?"

We don't actually know that. They might have limited sentience. Actually philosophers of the mind will point out we don't even know if ANY animal is sentient. But they almost certainly are. .

I watched a couple of these things ,and man, its quite clearly some of ol' hornet's victims are pretty distressed (Ie the scorpion trying to get the hell out of there)
