How killing can solve problems for you easy

A new kind of torture was beginning for me, the rest hadn't been enough.
New torments, new slavery!

Then a vigorous, deep voice called me. I got frightened and started running. Someone was running after me, a hand grasped me gently from behind. It was _____.
I surrendered.
"It's you?" I said unsteadily. "You gave me such a scare!"

I got frightened again. I suddenly recalled the story of Cain once more. The situation felt creepy and I started to cry softly. There was too much weirdness in the air.
"All right then," ____ smiled. "Get along home! We'll settle things yet. Though killing him would be the simplest thing. In such matters the simplest method is always the best. It's no good for you to remain in your friend Kromer's hands."
