You can still find food when you aren't receiving any, and besides that only applies in areas where the Abbey of the Everyman holds sway. On the White Cliffs or wherever the Overseers have their retreat there was at least one branded man, and since the guy reciting this didn't remember any brandings in his time that must have happened a fairly long time ago. And Corvo doesn't know that the High Overseer is going to become a Weeper; that's like like saying that someone who shuts the door on a homeless man knows he's going to contract West Nile Virus.

Brisby is very, VERY enigmatic when it comes to what he'll do with Lady Boyle. There is no debating that subject, and therefore there is plenty of debate about what he's going to do with her. For all we know he could just keep her locked in a room. He certainly doesn't kill her, because the Outsider TELLS us that she doesn't die of anything but old age unless Corvo kills her.

Corvo had no knowledge of how Slackjaw was going to deal with the twins until Slackjaw tells him.
