Tell the harpies that land on your bed post
That at the count of five, you'll roast them alive
Tell the devil it's time you gave him his due
He should go back to hell, he should shake in his shoes
Cause the mightiest, scariest, creature is you!
— Voltaire, "Goodnight Demon Slayer"
Here's your story: Demons over there, kill they ass.
The daemonic are without number, and their legions span the galaxy. But faith does not tire. Should it take us an eternity, the Ordo Malleus will find and exterminate them all.
— Lord Hephaestos Grudd, Warhammer 40,000
Every moment that the daemon, the heretic, the traitor draw breath is another moment of defeat for us, the most faithful of His warriors.

I am the Hammer.
I am the Hate.
I am the woes of Daemonkind.
— Battle Prayer of the Grey Knights, Warhammer 40,000'
Survivor: We're going to die here, aren't we?
Demon Hunter: No. Because as long as I'm here, they are the prey...and I am the hunter!

Like you said, humans are weak. We die easily. But no matter how weak we are, even if we're being chopped to bits or stabbed to death, we still want to live. I'm gonna give you a little taste of what it's like.
— Guts, Berserk, about to finish off the Baron of Koka Castle.
I love the smell of demon guts in the morning!

In the first age, in the first battle, when the shadows first lengthened, one stood. Burned by the embers of Armageddon, his soul blistered by the fires of Hell and tainted beyond ascension, he chose the path of perpetual torment. In his ravenous hatred, he found no peace; and with boiling blood, he scoured the Umbral Plains, seeking vengeance against the dark lords who had wronged him. He wore the crown of the Night Sentinels, and those that tasted the bite of his sword named him...the Doom Slayer.
