Is it cruel to eat roasted eel like this?

As we all know, Japanese people like to eat eels, especially in July every year. Almost every household eats eels. However, eel is popular not only in Japan, but also all over the world because of its rich nutrients. However, the practice of eel fish is different around the world. Recently, a video of a Korean restaurant roasting live eels was circulated on the Internet, which made people feel numb!

The video shows that an eel is barbecued on a charcoal fire. The terrible thing is that the eel keeps twisting and looks very painful. As the temperature of charcoal fire rises, eels twist more and more violently, as if trying to escape from this pain. But the cook on the side did not hesitate to dial it back with a spatula.
