Villain protagonist (Or at least lacks basic morals)

Again one of those i barely remember buuuut i think he was out for revenge and well that takes a bit of ruthfullness

Evil counter: 7/10

Ok so a death row inmate takes over the body of a highschooler and basically the friend (first mc) tries to make him idk not kill but it doesnt go as planned exactly

Evil counter: 8/10

This manhwa is CRAZY
Basically MC suspects her mom killed her brother, and is going to kill again, so she's out for revenge, but revenge is a longer plan, and when a new friend of her disrupts it, girly needs to manipulate

-She got some anger disorder (dont remember the name, although she's mostly calm n collected), there's schemes, bullying, and a lowkey hot psycho mum

Evil counter: 6/10 (it's very hard to measure, so see for yourself)
