People are being annoying remembering Slytherin exists and being all like durrrrr why would they make an evil house isn't it fucked up to get sorted into evil house at 11? Is roughly 25% of the population really evil? Yes. Yes they are. There should be a big snake stamp on all your government forms so everyone knows to keep an eye on evil house graduates and only put them in low security and limited public facing roles. Maybe some kind of shock collar that activates when it detects dark magic too.
