If a Jew wrong a Christian, what is his humility? Revenge! If a Christian wrong a Jew, what should his sufferance be by Christian example? Why revenge! The villainy you teach me I will execute, and it shall go hard but I will better the instruction.
What is how Shylock says - If I do something wrong to a Christian, they'll seek revenge. So, if they wrong me, I'll seek revenge like they've taught me to do by example. I'll just be better at it. - ?
