End a man?
Sure why not.
Show him to me.
Let me bury a sword in his chest or a bullet in his brain.
Let me feed him secret poisons and beat him with blatant fists.
Let me choke him snugly so I feel this whisper of his life as it departs.
Just let me at him.
Oh.
You meant, "Have you ever?"
In that case...
No.
