The wolf thought about it. It had been what it was for so long that it no longer remembered if it had ever been anything else. If it had been bitten, the scars and the knowledge that came with it were long gone.
It stopped it's threatening gestures and sat.
"I know no other cure." It told the man, calmly.
The human was just trying to protect others. Doing something unselfish. What the wolf wanted was completely selfish. It seemed as if the choice to make was the one that it most did not want to make. To allow this man to shoot and kill it. It thought about all the things it would not get to try. All the places it would not get to go. But it had started a bad thing with the young scared woman, and it needed to be ended. There were innocents involved. People whom it had never even encountered were now saddled with it's curse. It was reluctant to die, but knew that dying was the only way to save others. And it would be glad to die at the hands of this human, who was doing it unselfishly, instead of some other who might not be so kind.
The wolf pointed it's nose toward the gun.
"I hope that the thing you hold has more to it than a normal human weapon. I do not think ordinary bullets will do it. And in the head, please, make it quick."
It was a large target no matter how one looked at it, but there should be no problem with the man aiming at the wolf's head and hitting that target.
