I don’t want to cover for the murderer of course but the surrounding info suggests this woman was having a mental episode or worse. Asked to be put on leave, was denied, attacked a coworker, was not sent home but sat next to the principal like a child. Then stabbed a random kid. Fucking tragic but I guess that’s to be expected from a country such as SK which has one of the most brutal work cultures (and related suicide rates) in the world.
