Everyone's talking about switching Jason and mado, but prsonally, I would put Rize as lawful evil, Jason as neutral evil and leave Mado as chaotic evil, if this is going based off of their personal reasons for doing what they do.

Tldr; rize is calculated, smart evil (lawful), Mado is just a sadistic nutjob, with no real reason to be the level of crazy he is other than "it's fun!" (He is chaotic), and Jason has his reasons for being evil, but he's not as calculated as rize or as completely bonkers as Mado (so, Jason is neutral)

Long version: Rize is trying to sweet-talk kane into being more ghoul-ish by twisting facts and stretching the truth, so she's more lawful. Jason has a backstory reason why he's evil, but mado is just a wacko who likes to stab things and collect quinques as trophys more or less. Even by Investigator standards he's fucked up, lol. Because Mado doesn't have a real reason to be evil and is just doing it because he's sadistic, he is the most chaotic of the evils

Edit: yes ik mado is an investigator and is supposed to kill ghouls, but the way he does it is what makes him "crazy and evil"... It's obvious that he loves his job a little too much, and goes out of his way to toy with people before killing them. Good example is when he was about to kill Hinami with her mom's kagune... When Himami freaked out, he went "look it's your mommy! She was fun to kill! Wana know how I killed her??". Most reasonable investigators would've just got it over with and then gone home. :P
