The honourable function of friendship is mutual benefaction and gain. If you would stay friends with someone who would hurt you like that Dream, and steal 800,000.00 from you, then... you won't last long.
People like that are never your friends, right from the start. And if you stay friends with them, they will claim forgiveness, they may (though not very likely) even return some or all of what they stole, if that is possible, but then they will just hurt you again when they can profit from it.
Why did the man in Molotov's story go out to dinner and "Befriend" the other man? So that he could get close to that other man's wife. Why did the man in your parable befriend and impress his co-workers and then kill some of them? Because he was sick and evil. And don't debate the definition of "sick" with me either, there is no logical reason to do that sort of thing.
A friend will stick by you, yesss (uh oh I'm starting to sound like Nis here), but what you are saying about staying friends with someone who would hurt you like that is like continuing to shield someone from harm with your body as they maliciously stab you in the back.
Here's a small parable of my own... once there was a man, lets say he was a Paladin or a Priest even. Another man was hurt on the side of the road, his clothing stained with blood. "Help me" he said. The "Churchie" as they are sometimes called, went to this mans aid. "Stay calm, friend" he said. I am a doctor, I can help you.
The wounded man then stood up, and it turned out that the bloodstains on his clothing were nothing more than berry juice. The "wounded" mans compatriots surrounded the man who had stopped to help, they were grave robbers who had an alternate routine for anyone who passed by.
Now, I don't think anyone of intelligence can reasonably insist that the "wounded" man and the doctor were ever friends. One was being a friend, the other was being a trap. What Borknagar did, and what all of the people in the various parables have done, is just like this, only in a more extended manner.
If a friend steals 800,000.00 from me, he will no longer be my friend. All of my friends feel this way about me, and though it may even be slightly uncomfortable to speak of such things, it's true. And I would begin to wonder about the value of the friendship of anyone who insisted otherwise. They'd have to either be very deluded... or up to something.

Because I am nothing, I can be everything,
