This man, Makarov, is fighting his own war, and he has no rules. No boundaries. He doesn't flinch at torture, human trafficking, or genocide. He's not loyal to a flag or a country or any set of ideals. He trades blood for money. He's your new best friend.

The Joker: It's simple. We...kill the Batman.

Maroni: If it's so simple, why haven't you done it already?

The Joker: If you're good at something, never do it for free.

Ooh, business! That sounds like fun!

Grass grows, birds fly, sun shines, and brother brudda, I hurt people.

I do not care about the fight, only your pain!

"It's guns! I love guns! Machine guns? That's even better! This'll be fun! [...] Sounds like death! And danger! Danger! Danger! What's happening in the dining cart? Is there blood? Who's killing who? Where did they get shot? I have to see! Things are starting to get exciting! Yes yes yes yes yes yes yes yes YES!"
—Ladd Russo, Baccano

Lord Beelzebub has never seen
A soldier quite like me
Not only does his job, but does it happily!

Bullseye: I once tracked an Eskimo huntsman across 200 miles of frozen tundra on foot and killed him with an icicle made of my own frozen feces.

Kingpin: Who on earth would hire you to do that?

Bullseye: Nobody. I did that for fun.

Kingpin: You're a madman.

Bullseye: I kill people for a living. What did you expect?

Hobgoblin: You can't talk to me like I'm just some punk!

Norman Osborn: Before the wing and the weapons, you were just a punk! An ambitious hood in a mask. I made you the Hobgoblin, and now I'm unmaking you.

Hobgoblin: You owe me, Osborn. And I'll take the wing as my down-payment...

"Look kid, I'm not gonna bullshit you, okay? I don't give a good fuck what you know, or don't know, but I'm gonna torture you anyway, regardless. Not to get information. It's amusing, to me, to torture a cop. You can say anything you want 'cause I've heard it all before. All you can do is pray for a quick death, which... you ain't gonna get."

Jefferson: You drop that and we all die!

Psycho: And yet I don't seem to care. Must be why they call me PSYCHO!

Walter: I highly recommend pissing yourself... followed by a course of praying to your impotent god.

Jan: (breaks out in psychotic Evil Laugh) Now that's fuckin' great...! Cause I gotta tell you, plowin' through you people was really startin' to BORE THE FUCK OUT OF ME!!!
