It was fortunate that Kathrine was pretty good at procuring information.
They didn't have to torture the shepherd, but that was only obvious because Dilan's little demonstration broke the middle-aged man's will in an instant.
Tearing his right ear before naming a few cruelest ways to torture him did the trick.
Not everyone could pull it off, which was where Dilan's demeanor and appearance came into play.
He was more than enough to inflict desperation and fear within the hearts of other people.
As such, even if he knew that his death was inevitable, the shepherd told them everything as long as they promised to keep Dilan away from him.
Dilan didn't really care about the shepherd's life, but it was not possible for him to leave the shepherd alive either.
Thus, he was killed in a painless manner.
Nobody felt truly guilty for the death of the unarmed shepherd.
