it would depend on a few factors. If the people are cutting and maiming the animals just for fun, and to see them squirm, then as we are not primative animals and hold ourselves to higher standards, then it is animal cruelty. Basically the only one i had a real problem with was the frog one. It seemed like the person got it just to watch the frog suffer. The fish one, was not cruelty at all, but the way the people were taunting the fish was not right. You can cut off a fishes head, and it will still move and stuff....
So as long as the people are doing it to eat, and to not enjoy the suffering, then it is completly fine. (like a fisher man fillets a fish, the fish is still alive while its flesh is being cut off, but it is being done for the purpose of eating, and not just to watch it suffer.)
The squid is a good example, while it is sad that the squid was cut up the way it was, it was being done for the sole purpose of getting the meats, as fresh as possible, and such. wasnt like the frog where it was done to watch it squirm.
Its sorta like hunting....its fine to go out and hunt animals, but it is wrong to kill them solely for sport(like some people who may shoot a deer and then take its head or something, but not eat the meat.)
If you dont like this then dont be a carnivore, because even the frog one, was nicer that many animals would get in the wild being eaten by some other carnivore.....imagin being like the frog, only your sitting cut in half, slowly disenigrating in some dogs stomach, as after bitting you in half, he swallowed you whole.
Simply while it is very disgusting what these people are doing, in no way is it aThe taunting the fish is sorta borderline, and the frog is barely not cruelty. If any of this were done without the purpose of consumption it would be cruelty.
SIMPLY tortureing animals and killing them for no reason at all, is animal cruelty. While the methods may be cruel in killing sometime, it is not cruelty if the animal is killed for the purpose of being consumed.
