Shylock fails at law, Judaism, and revenge where Othello succeeds.

Evidence

In this, Shylock also fails to stand up to the comparison with Othello. Indeed, whereas Shylock consistently fails to exercise and even to understand the law-whereas he fails, as Martin Yaffe recently wrote, even to be a good Jew (“far from being a paragon representative of Uewish law], he is knowingly inconsistent with regard to it”), and whereas Shylock even fails to bring down the power of “Jewish” revenge, Othello never fails. — Gil Anidjar, The Jew, the Arab, 544
