So proud of him, he grew stronger. However I was always wondering why it doesnt bother him that much that Taeman actually killed people even if it is bad people. Like he was shocked a bit but he never confrontred him about the fact that ethically he did took the life of several young people. He accepted it and never questionned the fact that he could be himself in danger with a killer. Is he like morally questionable like Taeman ?
