Just like the title said, I'm looking for an evil mc or anti-hero that acts like a protagonist/good guy, but schemes behind the scenes.
This bastard scum mc is the best and fit your criteria, act like good dude, everyone believes him. Do good things (a lot of times no), but schemes a lot behind his friends Regressor Instruction Manual
yeah i second this one and it is at chapter 473 and 599 premiuim chapter so yeah you can read ahead if you pay or read mtl which is completely translated after you reached ch.472 , but the mc is pure evil and his most used method is scapegoat a good guy so you would hate him so much later on that you would ragequit the novel if you dont like pure scumbag mc
