Quote #10
ITHAMORE: Fie upon 'em, master.Will you turn Christian when holy
friars turn devils and murder one another?BARABAS: No, for this example I'll remain a Jew.
Heaven bless me! What, a friar a murderer?
When shall you see a Jew commit the like? (4.1.188-92)
So, Jacomo hasn't actually murdered Bernadine, but both friars have acted in such a way that it's been confirmed that they are "devils." They've shown they care more about money than about justice, and Jacomo, who actually thinks he has killed Bernadine, tries to run away. Not very Christian, Bernie.
