Yahweh, the Devil, and Job

[John V]

If the executioners reason for existing is to execute people and the supreme lawgiver removes the protective laws which protect said person from the executioner who is responsible for the execution?

You haven't shown that Satan's reason for existing is to execute people. There were plenty of other people in job's time who apparently didn't have a protective hedge about them.

Maybe a different analogy.

Yes, lets. I liquidate my investments, put the cash in my living room, and put a big sign up outside that says "Lots of cash inside and doors are unlocked," because I want to prove that people are good and won't steal the money. The guy who comes in and takes it is still guilty of stealing, despite my practical invitation to do so.
