Yiya killed her parents because of a joke. Is it vicious or helpless?

To say who was most respected by ordinary people in ancient times, there is no doubt that it was a scholar. There is a saying that everything is inferior and knowledge is high. There is also a saying that the only way to get ahead at that time was to study and become an official. This was the dream of all scholars at that time, and ordinary people were very envious of learned people and officials. But in the Spring and Autumn Period, there was a person who was very interested in learning. But he was naturally interested in cooking, and he put a lot of energy into his interest, but his friends and relatives around him were very disapproving. They laughed at why he had time to cook for others instead of studying. It was useless. But in the face of others' ridicule, he didn't refute this person at all, but secretly made up his mind to make these people regret it one day. This person is called Yiya.

Yiya is a chef in Qi State, and his cooking is very famous. He also opened a restaurant through his own technology and made a lot of money at that time. His fame gradually spread to Qi Huangong, so Qi Huangong called Yiya into the palace. Qi Huangong asked you, you are a chef. Can you help me? Yi Ya said happily, although I don't know any other skills, I am a very good cook and would like to be with you. So he stayed with Qi Huangong. He is also a very smart person. He can meet any requirements of Qi Huangong, which makes Qi Huangong feel very happy.

One day, when Qi Huangong was drinking his broth, he asked, "I don't know what human broth tastes like." Yi Ya returned home, wondering Qi Huangong's words. He felt that since Qi Huangong made this request, he must satisfy him, but he couldn't just kill others and spoil the broth. At this time, he saw his 4-year-old son, so he killed his son and made broth for Qi Huangong. This is a very cruel thing, so he can say that he is.
