"When you're pushed, killing's as easy as breathing."

Mike Toreno: Look, I spoke to the big man. You've got clearance to eliminate these fuckers. How's that?
Carl "C.J." Johnson: Man, kill Government agents?!
Toreno: Kill, schmill... C'mon, don't look at it that way, will ya? Think of it as pest control. It works for me!
Mizo: You have a habit of leaving people to die, don't you?
Jak: You get used to it.
With every man I kill, the farther away from home I feel.
— Capt. Miller, Saving Private Ryan
So what's that make? Twelve, fifteen counts of Self-Defense With An Automatic Weapon? I'm losing count, and I don't think the cops are going to buy it. I better just keep quiet about this when I get out. I'll have to fight my urges to brag about it when I get a new job.
Just. Gets. Easier.

Dryden: How did he die?
Bond: Your contact? Not well.
Dryden: Made you feel it, did he? Well, you needn't worry. The second is— [gets shot by Bond]
You know the first time, the first time you do it? You're scared. Blood's pumping. Your head's going a hundred miles an hour. You feel such power and strength. And after you get that feeling, you just want to do it again and again. It's like a drug. Each time it gets a little easier. First girl, I couldn't look in her eyes. I had to turn away, but now, it is so fucking routine. I can look right at you, I can stare right through you, and I can pull this fucking trigger.
— Jack Carter, The Hitchhiker
Unfortunately, killing is just one of those things that gets easier the more you do it.
— Solid Snake, Metal Gear Solid
I don't enjoy killing, but when done righteously, it's a chore like any other. And practiced hands make for quick labor.
—Joshua Graham, Fallout: New Vegas
Now if you have a taste for this experience
And you're flushed with your very first success
Then you must try a twosome or a threesome
And you'll find your conscience bothers you much less
Because murder is like anything you take to
It's a habit-forming need for more and more
You can bump off every member of your family
And anybody else you find a bore
— The Police, "Murder by Numbers"
Capt. Kanril Eleya: At ease. This your first time in a real fight?
Ens. Arak Esplin: Yes, ma'am.
Eleya: How are you feeling?
Eleya: Yes, I'm serious.
Esplin: During the fight, I was scared.
Eleya: And now?
Esplin: Numb, maíam. How am I supposed to feel? I just killed people.
Cdr. Tess Phohl: No, you didnít; I did, but thatís not important right now. Youíre feeling about what the skipper and me expected. Right, maíam?
Eleya: (nods, puts hand on Esplin's shoulder) Youíll be fine. Iím not going to rely on clichť here: the first battle isnít the hardest, itís just the first. And frankly, as pathetic as that one was, I guarantee the next will be harder. You do your job and work with your crewmates and you get through. The rest is up to the Prophets.

Elizabeth: Do you ever get used to it? The killing?
Booker DeWitt: Faster than you can imagine.
