Viktor said nothing for a long moment. It was true that Jon wasn't a killer, but giving someone a fate that was probably worse than death, even if that someone was a thing and not a person, said something about Jon's mental state. Viktor was in no position to pass any moral judgments on Jon though. How did you explain that you had essentially fed an actual living person who was strong and vital to the hexcore? Do you say you felt guilt over it? That guilt wasn't enough to let you destroy the hexcore so it didn't matter much in the end. Viktor kept the same carefully blank expression as he looked at Jon.

"Is that something you often do?"

He meant the sacrificing part, but the question was definitely open to interpretation.
