I never get more hate than when I say “hey, this toxic DM behaviour is bad and you shouldn’t do it.” This time, it’s “responding to violent PCs with an unreasonably powerful NPC out of spite just reinforces a player vs DM mentality.”

See also “the illusion of choice isn’t a brilliant trick, it just removes player agency” and “if one person’s idea of fun doesn’t match the rest of the group, remove that person, even if that person is you.”
