Who are the talented and immoral figures in history?

There are four great calligraphers in the Northern Song Dynasty, namely Su Shi, Huang, Mi and Cai, referring to Su Shi, Huang Tingjian, Mi Fei and Cai Xiang. Some people think that "Cai" originally refers to Cai Jing, but because Cai Jing was a corrupt official in the Northern Song Dynasty, later generations changed Cai Jing to Cai Xiang because of his "bad conduct". How greedy is Cai Jing as a corrupt official? Cai Jing's private life can be summarized as "luxury" in one word. For example, according to historical records, Cai Jing especially likes to eat a kind of food called quail soup. Cai Jing can kill hundreds of quails by eating quail soup once a meal. Cai Jing can eat so much! Not exactly. People don't eat whole quails, or even quail thighs. He killed a hundred quails and wanted quail tongues. The cost of making this quail soup was about equivalent to the living expenses of ten families at that time for one year. It can be described as luxury.
