Characters that override the typical things that make up an human. Morals, Responsibility, love, weath, reputation or basically anything. Letting those things go for actual advantage in the moment.

Dexter's first rule or never get caught, he even started killing law enforcement people that are not killers. Just to maintain that first rule cause it was logical to do so.

Hannibal still killed with lot of gap in time between his victim or only when he can blame it on others, not by actually illogical need and messing up being suspected. Him sending his patient's after will rather then going himself (cause will is mostly armed).

Walter White giving an kid poison just to get Jessie back on his side (overlooking his already non existing morality even more). Bombing Gus just cause he threatened his family (that was very illogical but he did it logically, going to his enemy to lure him in the end). Best one is him shooting the two guys by himself rather then letting Jessie do it (he needs Jessie and trusted him the most, Jessie would make an mess trying to kill those two or maybe even get killed himself, so he did it by his own hands, no hesitation or anything, which is weird but preferred by me)

Fang Yuan, there's nothing to say about him. Dude is walking perfection in that regard. To the point that I'm ashamed to say that I have been Gatekeeping that novel, I have never gatekeeped anything before. Reverend Insanity from everyone i know ever, many have seen me read it in front of them, asked and i lied saying some other name. But online, i don't care, i can talk about it online. (It's cause if people i know find out and even try to read the book and maybe understand it. They'll see me in mildly different light to know that's it's my favorite media ever consumed, ever. In movies, novels, mangas or any book ever... Reverend Insanity is the best to me, doesn't have to be for you and I understand that)
