What is the worst person you have ever met?

One of my primary school classmates, not long after giving birth, his mother died, and his father married his stepmother and gave birth to a boy. I went to her house to play. In winter, I sleep in a bed made of straw, and my clothes are patched. The shoes I wear in winter show my toes, shivering with cold, and my stepmother won't give me money to take a bath (in the 1970s, I couldn't wash them at home). There were lice on her head, and a girl shaved her head. Her stepmother asked my classmates to climb on the ground and ride horses for her stepmother's children. What is even more exasperating is that she never gets enough to eat and often cries when she is hungry. My mother often secretly gives her steamed bread to eat. Later, in order to get rid of this family, she graduated from junior high school and went back to her hometown to marry a farmer (we are registered in Chongqing), thinking that this would be better. As a result, I met the wicked mother-in-law, forcing her to break up and share all her debts. It is estimated that she will be in this life.
