Lawful Chaotic - loophole abuse. their goal is to carry out as many zany shenanigans as possible in an absolutely nonpunishable manner.
Chaotic Lawful - malicious compliance. dredges up obscure laws that haven’t been implemented in decades or centuries and insists on following them. thrives on inscrutable bureaucratic labyrinths.
Good Evil - the token evil teammate. a missing stair. an objectively terrible person but charming or useful somehow so people keep making excuses for them.
Evil Good - always does the right thing, but, like, in the least comfortable way. call them in for big, big problems, and then spend a year wondering if it was really worth it. their approval fills you with shame.
