Combine the whole work and tell me what kind of person Shylock is.

Shylock is a bourgeois usurer. In order to make more money, he showed his fierce face in the court in Venice. "I bought this pound of meat from him at a great price. It belongs to me. I must take it." Like all misers, greed is its nature. Shylock refused to pay twice or even three times the loan, but insisted on cutting off a pound of meat from Antonio, a businessman, because Antonio did not charge interest when lending money to others, which affected Shylock's usury industry, so he wanted to take the opportunity to retaliate and kill Antonio, so that his usury industry could run smoothly and accumulate more wealth. Shylock, as a typical image of a miser, has a sinister personality. When the court mediates to ask Antonio, the borrower, to pay him twice or even three times the money, Shylock sinister said, "Even if each of these 6, dollars can be divided into six parts, and each part can be turned into one, I don't want them. I just want to be punished according to the contract." As he spoke, he sharpened his knife on his shoe, always ready to cut off a pound of meat from Antonio's chest, brutally killing Antonio, and stubbornly, without any sympathy.
