how is shylock viewed as a comedic person in Merchant in Venice

Shylock hates Antonio because of his antisemitism, shown when he insulted and spat on Shylock for being a Jew. Additionally, Antonio undermines Shylock's moneylending business by lending money at zero interest. Shylock proposes a condition for the loan: if Antonio is unable to repay it at the specified date, he may take a pound of Antonio's flesh. Bassanio does not want Antonio to accept such a risky condition; Antonio is surprised by what he sees as the moneylender's generosity (no "usance" — interest — is asked for), and he signs the contract. With money at hand, Bassanio leaves for Belmont with his friend Gratiano, who has asked to accompany him. Gratiano is a likeable young man, but is often flippant, overly talkative, and tactless. Bassanio warns his companion to exercise self-control, and the two leave for Belmont and Portia.
