Im looking for å mc that kills without being a wuss and cares for as few as possible possibly like eminence in the shadow but maybe less comedy more manipulative genius plus op strength?

So something like Fukushuu o Koinegau Saikyou Yuusha wa, Yami no Chikara de Senmetsu Musou Suru?

~4400 manga completed
~1700 ongoing...

Akai Kiri no Naka kara

Just note that both this and the manga Aremon suggested are incredibly edgy purely for edginess' sake, never read Eminence so I'm not sure if that's a common trait for it as well.

Freesia Should fit at least the first part.

Seconding Akai Kiri no Naka kara as well, although I agree it's pretty much just fun.

It's been a while since I read them but if I recall correctly they should fit your description.

Aku no Kyouten
Ana Satsujin
Innocent Devil (I feel like this one was more focused on the psychological aspect instead of killing. But not 100% sure.)
