What if I want to step on a hermit crab walking along the beach?
You want to step on the hermit crab intentionally?
I want to eat it, I've roasted all crustaceans before.
It's understandable to not waste potential food. Crabs are great food.
I want to eat it while it's alive and in pain. I think slow roasted alive is how they eat it in China.
While it's fine to eat crabs, it seems that you will delight in the suffering and pain that the animal will experience. This is wrong and cruel.
