Demonizing the Jew

I found it interesting how Marlowe decides to demonize Barabus - quite literally even. Barabus often references the fact that he is "framed of finer mould than common men...For evils are apt to happen every day." At the start of the play, Machevill says that Barabus' "money was not got without my means." Their tie is more closely exposed a few lines later: "And let him not be entertained the worse / Because he favours me." Given the Machiavellian stereotype - willing to do anything to succeed, even the ruthless and immoral - one could argue the evilness of the Machevill in this play. In fact, one might view Machevill as the devil, and Barabus as having sold his soul - he does in fact have much more wealth than anyone else, enough even to buy the entire island of Malta, but doesn't wish to do anything with it but hoard it. And if Barabus is a minor demon of the satan Machevill, I guess that makes Ithamore a sort of imp, willing to do his master's bidding, his dirty work, if you will (like poisoning a nunnery...). In fact, I think Marlowe uses the dialouge between Barabus and the other jews to set Barabus apart from jews in general as a particularly evil figure; he is evil for evil's sake, not because he is jewish, as is supported by the stark contrast between Barabus and the other jews in the play.
