So there’s another possibility floating around, in regards to this episode title. Here’s a quote from “The Count of Monte Cristo” by Alexandre Dumas:
“But,” said Franz to the count, “with this theory, which renders you at once judge and executioner of your own cause, it would be difficult to adopt a course that would forever prevent your falling under the power of the law. Hatred is blind, rage carries you away; and he who pours out vengeance runs the risk of tasting a bitter draught.”
