Chapter 13 The Boy In The Striped Pajamas

         In chapter 13 in The Boy In The Striped Pajamas, Shmuel admits, " Lieutenant Kotler. He scares me." I think that Shmuel is afraid of Kotler because I think that he is the one who harshly seprated his Dad, brother and himself and his mother. That or he killed a relitive or friend. Kotler seems to scare most people with exceptions of a few. Please comment on why you think Kotler scares Shmuel and Bruno or just comment on this quote.
