Quote #7
Why, is not this
A kingly kind of trade, to purchase towns
By treachery and sell 'em by deceit?
Now tell me, worldlings, underneath the sun
If greater falsehood ever has been done?(5.5.46-50)
Who's the boss? Barabas! Well, for a few minutes, anyway. This comes late in the play, by which point the stakes have been upped from Barabas sneaking a bag of gold out of his house to gaining control of all of Malta. Even here, though, Barabas isn't as interested in actually ruling Malta as he is in the awesomeness of his plot.
Quote #8
Leave nothing loose, all leveled to my mind.
Why, now I see that you have art indeed. (5. 5.3-4)
Barabas is ordering his carpenters to build the mechanism he's going to use to murder Calymath. This is kind of cool because we get to see Barabas's plot in real life. Instead of just quietly plotting and playing people off of each other, he's escalated to "leveling the world to his mind." He's not just fitting the plots to his environment; he's changing the environment to fit his plots. (In other words: he's totally terraforming Mars.)
Quote #9
Barabas: […} Say, will not this be brave?
Ferneze: Oh, excellent! Here, hold thee, Barabas.
I trust thy word, take what I promised thee.[Ferneze offers Barabas the money again]
Barabas: No, Governor, I'll satisfy thee first… (5.5.41-44)
Ferneze trusts Barabas about as far as he can throw him (not far), but he knows there's no one better when you need to build a nefarious death-trap. Barabas has the market on nefarious death-traps cornered. Pro tip to Ferneze: if Barabas is refusing money, though, you'd better watch out.
