I want to read a manga where the main Charater can kill a crying child without remorse,
or I'd atleast want him to have the madness simialr to Anducar from Hellsing (btw he could do it) or Shimazu Toyohisa from Drifters (that insanity is something)

I do not remember more manga I've read like these.
It doesn't mather what Space Time it is or if its Sci-Fi or Supernatrual or something else.

Thank you for taking the time to read.

You could try Freesia and then maybe Black Lagoon.

Anducar sounds a bit too exotic imo, you cant even read that backwards. 😐

I think the characters in Koroshiya Ichi , Battle Royale and Mirai Nikki are kind of like that.
Maybe even Banana Fish - though I'm not so sure about that.

want to add
TWIM

and i second Freesia, Battle Royal, Black Lagoon and Mirai Nikki

I'll take a Look at them, Thank you for your time

Quote from purple716

Is there any manga where the male lead has an illness known as stomach ulcers.Yaoi are fine top.

The guys from Burning Hell. <3

If the main does n't have to be human, then Fourteen would work.

If you can go back in time and kill Hitler, then Light would totally kill baby Hitler.

Maybe Togari

Does it have to be the "main" main. Or can it be one of the main characters? If that makes sense? XD Anyway, here are some I think might fit;

Tokyo Babylon
Pet Shop of Horrors
Shounen Zanzou
Yami no Matsuei
A Night of a Thousand Dreams

shamo is the ultimite one your looking for. It start by the main character killing his parents.
