It's worth keeping in mind that, if a boss needs to be killed, that's work for the BOFH. If the boss has to pay the BOFH and go away, that's not work. It's logical to encourage not having to use violence just for laziness. As for the fear levels, I don't think there's any way for them to fall low enough for any risk to arise; the duo have already destroyed so many people that it's hard to imagine how people could forget.
